基于卡尔曼滤波模糊PID控制算法设计了汽车离合器综合性能试验台的转速控制系统。设计了试验台的总体结构并建立了转速控制系统的数学模型。转速控制系统是试验台控制的关键,针对转速控制系统干扰力矩较大和控制精度要求高的情况,提出了一种基于卡尔曼滤波的模糊PID控制算法对转速进行控制,将模糊控制鲁棒性强与PID控制稳态误差小的优点结合起来,采用卡尔曼滤波对转速信号进行滤波处理,降低试验台工作现场的干扰。仿真及试验结果表明,该控制方法能够显著改善控制性能,系统获得了较好的稳态精度和动态特性。
The rotational speed control system of the integrative performance test platform of the automobile clutch is designed based on fuzzy-PID controller with Kalman filter. The structure of test platform is designed, the mathematical model of rotational speed control system is established. The rotational speed control system is the key to the control of Test Platform, and the fuzzy-PID control algorithm with Kalman filter is proposed for the rotational speed control against the big interference torque and the high control accuracy requirement. This algorithm takes advantage of the strong robust of fuzzy control and the small steady state error of PID control, and the rotational speed signals are filtered with Kalman filter in order to weaken the interference of test platform job site to system. The results of simulation and experiment show that the performance of control is obviously improved and the system has the good steady precision and dynamic characteristics.
