Auto Disturbance Rejection Control for Nonlinear Object

摘要：

　　For some nonlinear complex control objects,conventional PID is not able to acquire excellent control effect because of its inherent defects.As a new controller based on PID control technology,Auto Disturbances Rejection Control (ADRC) breaks through the limitation of the former technology,at the same time maintains its advantages.In this paper,these two methods are used for nonlinear object —two-step water tank respectively.Simulation and application results prove that ADRC controller has better adaptability and robustness when controlling the nonlinear time-delay object,and has capability to achieve no-overshoot and no-static-error control.
