本文对螺旋电机的建模和控制进行了研究。建立了螺旋电机的电压方程和运动方程。在此基础上，设计了螺旋电机的控制系统.该控制器由三部分组成：第一部分是螺旋电机专用的带反电动势补偿的PI电流控制器;第二部分是基于扰动观测器的PD控制器，用于直线运动和间隙运动的相互作用;第三部分是间隙位移平衡波动的零功率控制器。实验结果表明，该控制器能够同时实现独立的直线位置和间隙控制。
In this paper, modeling and control of spiral motor is proposed. The voltage equation and motion equation of the spiral motor is proposed. Based on this modeling, control system for the spiral motor is proposed. The proposed controller consists of three parts; the first part is PI current controller with back EMF compensation specialized for spiral motor, the second part is disturbance observer based PD controller for linear and gap motion interacting each other, and the third part is zero-power controller for equilibrium fluctuation of gap displacement. It is confirmed that the proposed controller achieves independent linear position and gap control simultaneously.
