Design of a PSO-based Sliding Mode Controller for Controlling Chaotic Brushless DC Motors with Model Uncertainty and External Disturbances

چکیده
In this paper, the problem of robust stabilization and chaos suppression of nonlinear chaotic brushless dc motors (BLDCMs) is investigated. We propose a PSO-based robust sliding mode controller for stabilization and chaos suppression of the BLDCM in the presence of both unknown model uncertainties and external disturbances. First, based on the Lyapunov stability theory, a robust SMC is designed to ensure the occurrence of sliding motion. Then, a PSO algorithm is applied to optimize the parameters of the proposed controller. An illustrative example is presented to verify the robustness and efficiency of the proposed method and to validate the theoretical results of the paper.
