Speed control of PMSM based on energy-shaping and PWM signal transformation principle

Speed control of salient pole permanent magnet synchronous motor (PMSM) is studied based on energy-shaping and port-controlled Hamiltonian (PCH) system theory. Firstly, the PCH speed control model of PMSM is established. Secondly, the desired equilibrium point of the system is obtained based on maximum torque per ampere (MTPA) control principle. Then the… (More)
