Extended State Observer (ESO) Based Control Strategy with Parameter Optimization for Brushless Doubly-fed Machine

Abstract

Abstract-This work is concerned with an extended state observer (ESO) based controller with parameter optimization for brushless doubly-fed machine (BDFM). An ESO based controller is proposed to deal with the complex inner coupling effect and external disturbance, which are hardly obtained in the practice. To reduce the workload of the parameters selection, an optimized parameter design method for the nonlinear ESO is proposed. Simulation results show that the proposed controller, which brings out an excellent performance and increases the robustness of the system, rejects the disturbances successfully and achieves the decoupling control of the system.
