Modeling and simulation of Active-Disturbance-Rejection Controller with Simulink

The way of modeling and simulation for Active-Disturbance-Rejection-Controller (ADRC) is discussed by masking subsystem and building user custom library in Matlab/Simulink, after studying the basic principle and structure of ADRC. In this way, the programming workload of researching ADRC can be reduced, and the complex blocks group in Simulink can simplify. The simulation example and results show that the modeling method is practical and validity.
