Abstract


Background/Objective: This paper enhances the responses of Permanent Magnet Synchronous Motor (PMSM) drive system with design of PI controller based on Nelder-Mead optimization Method implemented in Matlab environment and Optimization Toolbox. Methods/Statistical Analysis: The minimization requirements on control quality such as overshoot, settling time and steady-state error have been realized by choosing objective function based on ITAE criterion. The speed error for control of the speed of PMSM based on field oriented control is considered for implementation of ITAE criterion. Findings: The standard AC6 model (Field oriented control of PMSM drive) of MATLAB Simpower system is analyzed for optimal design of the coefficients of the PI controller. Improvements: The effectiveness of responses of torque, current and speed tracking are verified with random PI and optimized PI coefficients.
