摘要
鉴于自抗扰控制器存在结构复杂和跨阶控制抗扰性低等问题,提出一种新型抗扰控制方法。通过对线性(二阶)自抗扰控制器结构进行变形处理和改造,得到简单的线性抗扰控制器和高阶抗扰控制器,简化了抗扰控制器的结构;将高效率的正弦跟踪滤波器运用于抗扰控制器中,提高了控制器的抗扰性能。数学分析、仿真实验和实际应用的结果验证了所提出方法的正确性和有效性。
In view of problems such as complicated structures and low disturbance rejection characteristic of the active disturbance rejection controller(ADRC),this paper presents a kind of new-type disturbance rejection control method.By means of deformation processing and transformation for structures of the linear(second order)ADRC,it can obtain a simple linear disturbance rejection controller and a high order disturbance rejection controller,which means simplifying structures of the disturbance rejection controller.By using the high efficient sinusoid tracking filter for the disturbance rejection controller,it also improves disturbance rejection characteristics of the controller.Results of numerical analysis,simulating experiments and actual application verify accuracy and effectiveness of the proposed method.
