摘要
讨论了静电支承球形转子的精密恒速控制系统,该系统主要基于旋转磁场加转和锁相控制。阐述了控制系统的组成,分析了鉴相器、PD控制、加转系统模型并加以线性化,求出传递函数并分析特性,最后介绍了具体实验效果。
The issues of exact constant-speed control system for spherical rotor with electrostatic suspension are discussed. It is based on the wheeling magnetic field and the PLL control. The basic operation principle of control system is described. The phase-locked loop, the PD controller, the model of wheeling system and its linearization are analyzed. The transfer function and its characteristics are worked out. Finally, the experiment result is introduced.
