A Novel Control Method for Permanent Magnetic BLDCM Using ADRC—PLL Dual-mode Strategy

To solve the problem that the control dynamic response of high-speed rotor of magnetic suspended CMG used in large satellites and space-stations is slow,presented an active disturbances rejection controller-phase lock loop(ADRC-PLL)dual-mode control strategy.The fast dynamic response,low overshoot and high precision control for the permanent magnetic BLDCM was implemented by switching between the ADRC mode and the PLL mode.When the rotor speed is reaching the expected,the PLL mode is used to achieve the high precision control of the rotor speed,when the speed is out of the expected,the ADRC mode is switched to drive the rotor to the expected speed rapidly.The simulations and experiment results verified the valiv of the proposed approach.
