摘  要：针对大型卫星和未来空间站用控制力矩陀螺的高速转子控制系统动态响应慢的问题，提出了一种自抗扰-锁相环双模控制方法。通过电流转速双环自抗扰控制器和自抗扰锁相环控制器两种模式之间的切换来实现无刷直流电机转子转速的快响应、低超调和高精度控制。在期望转速点上通过电流环自抗扰转速锁相环模式实现转子转速高精度控制，在期望转速点外通过双环自抗扰控制器实现到期望转速点的快速跟踪。仿真和实验验证了上述方法的正确性和有效性。

Abstract: 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.
