摘要
针对气动加载系统压力跟踪控制中的强耦合性、强非线性、不确定性等问题,将跟踪微分器(TD)作为反馈滤波器加入到无模型自适应控制(MFAC)中。结合2种方法的优点,可以有效抑制外界干扰对系统带来的影响,获得更好的输出性能,提高控制系统的鲁棒性。在气动变载荷摩擦磨损实验机控制平台上进行了实验验证,与无模型自适应控制进行对比,实验结果表明,改进的控制器具有抗干扰性强、响应速度快、鲁棒性强等特点。
Aiming at the problems of strong coupling,strong nonlinearity and uncertainty in the pressure tracking control of pneumatic loading system,the tracking differentiator(TD)is added into the model-free adaptive control(MFAC)as a feedback filter.Combined with the advantages of the two methods,it can effectively suppress the influence of external interference on the system,obtain better output performance and improve the robustness of the control system.Compared with the model-free adaptive control,the experiment results show that the improved controller has the characteristics of strong anti-interference,fast response and strong robustness.
