摘要：
Considering the special characteristics of the automatic disturbance rejection controller (ADRC), with emphasis on the parameters and strong coupling among them, an algorithm is presented in this paper for tuning the parameters of the ADRC automatically. Aiming at the minimization of the control performance function, the algorithm learns an optimal set of controller parameter values of the ADRC by cost function, updating each parameter of the controller within a bounded interval probability density distribution constantly and making the probability density of the optimal control parameter maximum. The algorithm is applied to an open-loop unstable system and the industrial mechatronic drives unit (IMDU), the results of simulation and experiment show its validity.
