Advance Vector Control on Based Energy Shaping for control in Wide Speed Range and Quicker Dynamic Response

Based on the vector of the permanent magnet synchronous motor (PMSM) and in order to obtain the system operation of wide variable speed range, quicker dynamic response, the maximum torque per ampere (MTPA) control is often applied for the constant torque region, the flux-weakening control is used in the constant power region, moreover, the classical two closed-loop PI controller are often used. Recently, the energy-shaping nonlinear controller is increasingly used to control the nonlinear induction motor or PMSM, therefore, the comparison between both PMSM systems is devoted to research in this paper, one adopts the PI current controller, the other adopts the energy-shaping current controller. Both PMSM control systems are modeled based on the MATLAB/SIMULINK, and the system performances are tested and some conclusions are given.
