Simulation and Parameters Tuning of Second Order ADRC Controller in Simulink

Abstract:

Based on studying Active Disturbance Rejection Control(ADRC)technology, with MATLAB / SIMULINK as simulation platform, a simple second order system as a controlled object, Specifically discussed the establishment of system module using simulink model.By the way of designing system functions for dynamic algorithms such as Tracking Differentiator and Extended State Observer, Not only can change the system parameters and simulation results can be observed after parameters changed, the simulation process becomes simple and effective. And the relationship between parameters of ADRC and the plant dynamic characteristics are analyzed when the parameters are changed, where some principles for parameters tuning of ADRC and effective applications are provided. Finally, Through simulation examples shows that the method is practical and effective.
