Abstract: Linear switched reluctance motors (LSRMs) have been an attractive choice for direct-drive applications due to their low-cost and simple structures. However, LSRMs are difficult to control because of the highly nonlinear model. In this paper, a LSRM model, which takes the winding current tracking as a part of the LSRM model, is first proposed based on the two-time-scale method. According to this model, a basic yet effective two-degree-of-freedom controller is developed. The two-degree-of-freedom controller is as low cost as the conventional proportional-derivative (PD) controller but it has better the high frequency tracking capability than the conventional PD controller. Experimental results indicate that the LSRM model is effective for the controller design and the position tracking system with the proposed controller can track the position command accurately.
