Research on the Problem of ADRC Controller Parameters Tuning Based on Hybrid Optimization Algorithm

Auto- Disturbance- Rejection- Control(ADRC) controller is widely used in engineering field.ADRC tuning problem is a main difficult point of applying it.The performance of ADRC depends on tuning and optimization.The tuning problem is recast into a multi- objective optimal problem.We introduce a new Hybrid optimization algorithm for tuning and optimal ADRC,which integrate with MATLAB.The Hybrid optimization algorithm is based on Nonlinear Least Squares and NSGA- Ⅱ.The parameters of nonlinear ESO ADRC and LADRC are tuned.The result of simulation indicates the multi- objective Hybrid optimization algorithm is effective for tuning ADRC parameters.The good performance of ADRC is shown in the simulation.
