摘要
飞机舵机系统是一个液压伺服系统,由于液压伺服系统具有非线性和不确定性,普通的控制方法难以达到较好的控制效果。为了提高舵机控制器的控制效果,改善液压舵机系统综合性能,提出一种CA-CMAC与模糊PID并行控制方法用于飞机舵机控制系统。利用Simulink平台进行建模仿真,并与传统的PID和P1D与CMAC并行控制方法进行对比。仿真结果表明,CA-CMAC与模糊PID并行控制方法据有更好的控制效果,大大减少了系统响应时间。改进方法结合了CMAC与模糊PID的优点,提高了液压舵机伺服系统的综合性能。
As a hydraulic servo system, the tailplane actuator servo system combines the features of nonlinearity and uneertainity, and it will be difficult to have a better effect with general control methods. In this paper, we proposed a control method combining CA-CMAC with fuzzy PID, and applied it in the tailplane actuator control servo system, to improve effects of the controller and promotes comprehensive functions of hydraulic actuator systems. The result of simulation shows that, with the modeling and simulation of simulink, the method has the advantages of both CMAC and fuzzy PID, and promotes comprehensive functions of hydraulic actuator systems, in comparison with the tranditional PID and CMAC-PID control method.
