Abstract :
Nonlinear Auto-Disturbance-Rejection-Control controller tuning problem is investigated. The tuning problem is recast into a multi-objective optimal problem .The typical Nonlinear Least Square Method Levenberg-Marqudart algorithm and min-max optimization method is utilized to realize the optimal iteration. A new optimal mechanism is introduced which integrate simulink and optimization toolbox of Matlab. Based on this mechanism the parameters of nonlinear PD and extended state observer is tuned .The result of simulation indicate the multi-objective optimization tuning method is effective.
