High-Precision Spiral Motion Control of Linear Rotary Motor With E-shaped Stator

In order to improve the control precision of the spiral motion of linear rotary motor with E-shaped stator at low-speed condition, a novel high-precision spiral motion control approach is presented by adjusting the connection method of the nine phase windings, which can make it become a three-phase permanent magnet synchronous motor. The control system is built adopting model predictive control methods and active disturbance rejection control, which can have higher anti-disturbance capability.
