Active Disturbance Rejection Control (ADRC) is designed for uncertain systems with input and state delays. ADRC is composed of Tracking Differentiator (TD), Extended State Observer (ESO) and Nonlinear Feedback Control. It actively and systematically explores the use of nonlinear control mechanisms for better performance and is rather independent of mathematical models of the plants. Based on ADRC with a feedback block containing a filter, satisfactory simulation results are obtained.
