A self-tuning of a wavelet PID controller

Abstract

In this paper a self-tuning wavelet PID controller using wavelet networks is presented. The wavelet-based multiresolution PID controller was purpose by [8], the ability of this controller is to provide good rejection to disturbances and smooth control signal. One of its disadvantages is that the tuning gains are in trial or error mode. A wavelet network to identify the system and to tune the gains of the wavelet PID controller is proposed. To validate the proposed control system numerical simulation is performed for a motion control system.
