摘要
自抗扰控制器(ADRC)是针对非线性不确定系统提出的一种新型非线性控制器。在深入研究自抗扰控制技术理论的基础上,通过非线性系统的线性化和参数整合等方法设计出了优化ADRC,并给出了新的参数整定方法。MATLAB仿真表明,优化后的ADRC需调整的参数大大减少,调节过程也得到简化,但性能并未受到影响,对被控系统的不确定性和外扰有很强的适应性和鲁棒性。
Active disturbance rejection controller (ADRC) is a new type of nonlinear controller for estimating and compensating the uncertainties system. Based on studying deeply and systemically the theory of ADRC, the optimization active disturbance rejection controller was established by means of linearization of the nonlinear system and parameter conformity, then a new regulation of parameters for the ADRC was proposed. Simulation results showed that the regulation of parameters is simple and the parameter' number is greatly reduced while the performance of the controller is not influenced, and the system has good robustness and desirable control effect.
