Design of PIDNN adaptive disturbance rejection decoupling controller

In industrial control, there are a large number of nonlinear strongly coupled controlled objects with external disturbance. It is difficult to control the object of such a good effect with classical control theory. Aiming at the problem of disturbance rejection, decoupling and tracking control of this kind of system, PIDNN controller is adopted in this paper, and its weight correction algorithm is improved to eliminate the influence of local minimum value on control effect. The improved PIDNN has better adaptive disturbance rejection and decoupling control performance. The effectiveness is verified by computer simulation.
