Abstract

The invention relates to a control system and control method for a CMG (Control Moment Gyro) framework permanent magnet synchronous motor, and specifically relates to a control system and control method for precision of the rotating speed and bandwidth of a CMG framework permanent magnet synchronous motor, being suitable for various high performance servo systems, including a CMG framework system, based on a permanent magnet synchronous motor. By means of combination of sliding-mode control with a rotor field orientation vector control method, the control method for a CMG framework permanent magnet synchronous motor can improve the inhibiting ability of the system on the non-linear low frequency interference moment introduced by gyro moment, rotor static unbalance and other factors, and can improve the framework rotating speed control performance and the robustness of the system.
