Fig. <t>1.</t> <t>Simulink</t> simulation of <t>PID</t> controller 2.4 PID Parameter Tuning In PID control, it is important to achieve the best performance of the control system by properly adjusting the values of these three parameters. The three parameters are proportional coefficient (Kp), integral coefficient (Ki) and differential coefficient (Kd), which correspond to the three basic control behaviors of the controller, reflecting the response speed, stability and anti- interference of the controller. The specific role is as follows: The magnification of the proportional coefficient Kp control error is the most basic proportional controller in the control loop. The larger the proportional coefficient Kp, the faster the response speed of the controller to the error, but at the same time, it will also increase the stability of the system, oscillation and even instability such as oscillation. The role of the integral coefficient Ki is to eliminate the steady-state error of the control system and to compensate for slower changes. In general, a larger integral coefficient can reduce the steady-state error of the controller, but if the integral coefficient is too large, the system may have integral saturation, resulting in system failure (Zhang et al., 2024). The differential coefficient Kd is used to weaken the sensitivity of the controller output to interference and suppress the fast response of the system. The larger the differential coefficient

Simulink simulation of PID controller 2.4 PID Parameter Tuning In PID control, it is important to achieve the best performance of the control system by properly adjusting the values of these three parameters.

Fig. 2. Step response of PID controller After repeated parameter tuning, the final parameters of the PID are: Kp = 50, Ki = 0.8, Kd = 0.23, and the output waveform is the most stable. It can be seen from Fig. 2 that the system can respond quickly. For incremental PID control, such performance indicators have been able to achieve the purpose of stable control of smart cars. 2.5 Establish Fuzzy Control Rules In PID control, the system deviation refers to the difference between the actual output and the expected output, which is the so-called error. In general, the PID controller measures the error between the system output and the desired output, and calculates and adjusts the output signal of the controller according to the size of the error, so that the system output is as close as possible to the desired output. If the system deviation is large, it is necessary to use the proportional coefficient Kp to adjust the response speed of the controller to the error. If the system deviation is small, it is necessary to use the integral coefficient Ki to reduce the error, or use the differential coefficient Kd to suppress the oscillation of the system. The controller needs to use these three coefficients flexibly according to the actual situation and system characteristics to achieve the control objectives. Therefore, the key to the success of the fuzzy PID control system is how to quickly and accurately realize the self-adjustment of the three coefficients of the PID, and fuzzy adaptive control of the speed of the intelligent vehicle (Chen et al., 2024).

Fig. 9. Adaptive fuzzy PID control response diagram It can be seen from the simulation result Fig. 8 that compared with traditional PID control and incremental PID control, adaptive fuzzy PID control has better control effect and higher stability. Under different working environments and operating conditions, the adaptive fuzzy PID controller can automatically adjust the control parameters to achieve more accurate and stable control. In comparison with incremental PID control, the overshoot of adaptive fuzzy PID control is almost 0, indicating that adaptive fuzzy PID control greatly improves the rapid response and robustness of the control system. This also further proves the superiority and applicability of adaptive fuzzy PID control in automatic control systems. (2) Anti-interference test of fuzzy PID control In the stable state of the system, if a large speed or sharp deceleration is suddenly given, this instantaneous change will cause great interference to the control system and cause further instability of the system. However, with the support of adaptive fuzzy PID control, the system can adapt to different load and working conditions by automatically adjusting the control parameters, so as to achieve fast response and strong robustness. For example, after giving the system a large speed signal, the control system Fig. 9 shows that the gain is generated, but the system is quickly stabilized by the support of
