Performance Robustness Comparison of Active Disturbance Rejection Control and Adaptive Backstepping Sliding Mode Control

Active disturbance rejection control and sliding mode control are two control approaches which are claimed to have good ability and strong robustness in the control of the systems with internal uncertainties and external disturbances. But the systematic comparisons of these two control schemes are lacking in the extant literatures. In this study, Monte-Carlo experiment is adopted to test the performance robustness of these two control schemes based on the same nominal disturbance rejection ability. Simulation results show that the second-order linear active disturbance rejection control has very good performance robustness, especially for the plants with integrating element, the high order plants and the nonlinear plants.
