Abstract
Aim at the question that there is not an integral action in the feedback control gain of the conventional direct prediction control law for permanent magnet synchronous motors which lead to a steady-state current error and weak robustness of the system, the integral action was added into the conventional predictive control law in this paper, the integral gain factor was obtainedby assigned the desired poles of the closed system. The proposed improve predictive control law within the integral action can reduce the static current error and the robustness of the system can be enhanced against the model parameters mismatch in theoretically. Simulation results based on Matlab/Simulink platform has verified the feasibility and correctness of the improved algorithm.关键词
