Abstract

A passivity-based controllers with integral actions is proposed to control the current loop of permanent magnet synchronous motor (PMSM). The Port-controlled Hamiltonian system with dissipation (PCHD) model of permanent magnet synchronous motor with voltage disturbance is established by introduction of the state error and the integral action. The Lyapunov function is constructed to analyze the stability of system under the condition of constant and time-varying perturbations. This control strategy can obtain the control law of the d, q axis and integral action, and can keep an exponential convergence of the closed loop system. Experimental simulation results show the proposed control strategy can effectively suppress the constant and time-varying disturbances, eliminate the steady-state error, and improve the robustness of system.
