The Control of an IPM Synchronous Motor Drive Based on Using the Double-Regulation Control Mechanism

In this paper, based on using a double-regulation control mechanism, we consider the control of an interior permanent-magnet (IPM) synchronous motor drive which may be interfaced by uncertainty and/or disturbance. The method can be summarized as follows: First, for the system which contains uncertainties and disturbances, we design the integral feedback by introducing a dynamic mechanism to adjust its gain so that the disturbances and uncertainties can be eliminated. Second, for the remaining part of the system, we choose the proper state feedback mechanism to ensure the required performance. Lyapunov analysis is provided to guarantee the stability of the relevant control system. Simulation results indicate the effectiveness of the method.
