Simulative Analysis of Fuzzy PID Control Algorithm for Antiskid Driving System of Tractor Based on Slip Ratio

对基于滑转率的拖拉机驱动防滑模糊PID控制算法进行了仿真分析。首先建立系统的数学模型,并用Matlab/simulink建立计算机仿真模型,然后设计系统的模糊PID控制器,并进行了仿真分析,观察控制效果,同时用PID控制算法、模糊控制算法进行仿真研究,分别进行响应性、抗干扰性、适应性的对比分析,对比发现,模糊PID控制算法较为合适。

In this paper, the simulative analysis of fuzzy PID control algorithm for the antiskid driving system of tractor based on slip ratio was carried out. Firstly, the mathematical model of the system was built, and the computer emulational model was set up by using Matlab/simulink. Secondly, the fuzzy PID control algorithm for the system was designed, and it was simulated and its control effect was observed. At last, the PID controller and fuzzy controller were also designed and simulated, and the responsiveness, adaptability and anti - interference performance of these three controllers were compared. As a result, the fuzzy PID controller was more suitable for this system.
