Robust Tracking for BLDCM System Based on Unknown Differentiable Deadzone Nonlinearity

Abstract:

In this paper, trajectory tracking control of the brushless DC motor system (BLDCMS) with parameter unknown deadzone nonlinearity and viscous friction is investigated. Firstly, a global differential homeomorphism based on the recently established differentiable deadzone model is developed to linearize BLDCMS. Then, a model reference robust controller is presented to suppress the uncertainties. Finally, uniformly ultimate boundedness of the closed-loop system is proved and simulation results show validity of the proposed controller.
