摘要：

For the speed control of non-salient pole permanent magnet synchronous motor (PMSM), a novel nonlinear flux weakening control method of port controlled Hamiltonian (PCH) has been proposed in this paper. The control scheme is designed by the PCH control and L2 gain strategies. The calculating of the equilibrium point in the system uses the maximum torque/current principle below the base speed and the flux weakening principle above the base speed. Load torque disturbance always exists in the practical PMSM speed control system and using L2 gain to attenuate it. The PMSM speed control system is asymptotically stable. Simulation results show that the motor can achieve higher speed region with response rapidly, and has good attenuation ability to load torque disturbance.
