Based on the vector control of the permanent magnet synchronous motor (PMSM) and in order to obtain the system operation of wide variable speed range, 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...
This paper designs a novel control method for energy efficient and wide speed range drive of the PMSM. The proposed method includes several parts: (1) using a PI speed controller to create a signed current norm value as input of the command converter. (2)The command converter can simply and accurately generate an analytical current command according to the current control standard satisfying the maximizing/current...
