A design scheme of fuzzy-PID controller is put forward. The simulation analysis from matlab indicated that the dynamic performance of fuzzy-PID control algorithm is better than that of usual PID. Experimental result of smart car show that it can follow the black guide line well and fast-stable complete running the whole trip. Keywords — fuzzy-PID; smart car; fuzzy controller; fuzzy control 1 Introduction In recent years, many countries are developing unmanned vehicle technology. This [1] gives birth to many new theories and applied technology. Referencepresents the theory of turn ahead which uses real-time monitoring speed to change the turn-in point dynamically, then it implements the control strategy to achieve a perfect characteristics of [2] steering. Referenceuses edge detection algorithm to extract track information and adopt [3]P control. Reference proposes a efficient, good anti-jamming and adaptive image processing dynamic algorithm which effectively solves the out of track caused by the [4] changes of ambient light and track. Referencereconstructs spatial relationships of track and calibrates camera using nonlinear optimization, then it can measure lateral deviation accurately. The above improve vehicle performance in one way but they are all lack of characteristics of car movement and based on lots of experiments. A fuzzy-PID control algorithm and a design scheme of fuzzy-PID controller are put forward in this paper. At last, the experimental result is given out to prove the validity of fuzzy-PID. 中英文翻译 2 Hardware system design To implement the design of fuzzy-PID algorithm, it’s necessary to design a hardware system of smart car. Smart car would have a smart control unite which contain detection of guide line, steering angle value, speed value and so on. See details in Fig.1. Fig.1 The functional block diagram of smart car 3 Basic principle of fuzzy-PID It’s difficult for usual PID control algorithm to achieve the best effect. Because, the parameters Kp, Ki, Kd can’t adjust to different object or different state of the same object. Fuzzy control is based on fuzzy set and fuzzy logic. Without precise mathematical model it can determine the size of controlled variable according the rule table organized by experience. In general, fuzzy control input variables are based on system error E and error change EC, which is similar to PD control. Such control might have a good dynamic characteristic, but the static performance is not satisfactory. Combining fuzzy control and PID control, this would make a system have both flexibility-adaptablity of fuzzy control and high accuracy of PID control.Fig.2 shows the structure diagram of fuzzy-PID control system, in which fuzzy controller is responsible for selecting a different PID parameter to improve the local performance thus increasing over all performance. 中英文翻译 4 Design of fuzzy-PID controller Speed drive motor controller design is similar to the following example for steering gear controller design. Fuzzy controller consists of fuzzification, fuzzy-inference and defuzzification, which are based on the knowledge base.[6] Controller input error and error change, output the parameters Kp,Ki,Kd. Suppose the fuzzy set for E is{NB,NM,NS,NO,PO,PS，PM,PB}; the fuzzy set for EC、 Kp、Ki and Kd is{NB,NM,NS,ZO,PS,PM,PB}. The linguistic meanings are: NB = negative big, NM = negative middle, NS = negative small, NO = negative zero, ZO = zero, PO = positive zero, PS = positive small, PM = positive middle, PB = positive big. So the membership function curves of fuzzy variables E、EC、Kp、Ki and Kd are shown in the Fig.3-Fig.7: 中英文翻译 中英文翻译 It’s necessary to establish rule table after finishing fuzzification. According the description of rule table, 56 fuzzy conditional statements can be summed, which look like If (E is PB) and (EC is PB) then (Kp is PB) (Ki is ZO) (Kd is PB). See details in Tab.1-Tab.3. Then, the last step is defuzzification and making a lookup table. During fuzzy control, 中英文翻译 the lookup table would be embed into the program. Suppose input value is fixed, the corresponding output value would be found in the table. Actually, this would save much computing time, and the control would become simply. 中英文翻译 5 Analysis of experimental results 中英文翻译 [7]Experiment used the steering gear model provides by reference. The simulation circuit were shown in Fig.2. The usual PID and fuzzy PID algorithm were all simulinked in the Matlab. Responding curves obtained were shown in Fig.8 and Fig.9. The experimental result show that compared with the usual PID, the responding time of fuzzy-PID algorithm is shorter without over swing. The system dynamic performance is improved significantly. 6 Conclusion and outlook This paper provided a design scheme for controlling a smart car, which is proved practically and superlatively though experiments. Unmanned smart car is due to the development of computer technology, pattern recognition and intelligent control technique. Many countries and research groups are doing research in the area. But it’s a complicated system, which involves a number of technologies. So the development of each technology is important, for it would become the bottleneck of the development of smart car. Device Overview S12XS Family 1.1 Introduction The new S12XS family of 16-bit micro controllers is a compatible, reduced version of the S12XE family. These families provide an easy approach to develop common platforms from low-end to high-end applications, minimizing the redesign of software and hardware. Targeted at generic automotive applications and CAN nodes, some typical examples of 中英文翻译 these applications are: Body Controllers, Occupant Detection, Door Modules, RKE Receivers, Smart Actuators, Lighting Modules and Smart Junction Boxes amongst many others.The S12XS family retains many of the features of the S12XE family including Error Correction Code(ECC) on Flash memory, a separate Data-Flash Module for code or data storage, a Frequency Modulated Locked Loop (IPLL) that improves the EMC performance and a fast ATD converter.S12XS family delivers 32-bit performance with all the advantages and efficiencies of a 16-bit MCU while retaining the low cost, power consumption, EMC and code-size efficiency advantages currently enjoyed by users of Freescale’s existing 16-bit S12 and S12X MCU families. Like members of other S12X Families, the S12XS family runs 16-bit wide accesses without wait states for all peripherals and memories. The S12XS family is available in 112-pin LQFP, 80-pin QFP, 64-pin LQFP package options and maintains a high level of pin compatibility with the S12XE family. In addition to the I/O ports available in each module, up to 18 further I/O ports are available with interrupt capability allowing Wake-Up from stop or wait modes. The peripheral set includes MSCAN, SPI, two SCIs, an 8-channel 24-bit periodic interrupt timer, 8-channel 16-bit Timer, 8-channel PWM and up to 16- channel 12-bit ATD converter. Software controlled peripheral-to-port routing enables access to a flexible mix of the peripheral modules in the lower pin count package options. 1.1.1 Features Features of the S12XS Family are listed here.

The HCS12 CPU is identical to the MC68HC12 and is referred to in most documents as CPU12. Another factor to consider is that CPU12 is upward compatible with the MC68HC11 CPU. The MC68HC11 and the MC68HC12 will be referred to as the HC11 and HC12 respectively in this module. Like the HC12, the HCS12 CPU maps all registers and peripherals into a single linear address space, providing efficient memory access. Since the HCS12 family supports up to 1 mega byte of address space, a paging scheme has been implemented to access as many as 64-16K page windows. This provides system designers with the memory needed to satisfy many applications. The HCS12 CPU instruction set extends the HC11 instructions for data movement, data manipulation, enhanced arithmetical operation, and branching and control logic. In addition, the HCS12 model adds several new addressing modes for a total of sixteen addressing modes. Although most of the HCS12 family members have on-chip Flash and RAM, which are ideal for single chip solutions for many applications, the system designer can configure the device to access additional memories externally. More Features • The HCS12 has an identical programmers model to M68HC11/M68HC12 – No new registers – No changes in interrupt stacking order – Muxed and non-muxed external interfaces • The HCS12 can reuse existing software source code. - Note: timing loops change due to new clock frequency, Byte counts and instruction cycle times. • The HCS12 has improved performance when using new instructions. • The HCS12 reduces interrupt latency. • The HCS12 increases math speed. • The HCS12 increases performance. – Instruction queue data increases performance 中英文翻译 – Instructions execute faster while remaining deterministic References [1] WEI Yu Hu, SHI Chen Yu, JIANG Jian Zhao and CHANG Hua.
