Abstract

The utilization of position sensor reduces the system reliability of switched reluctance motor (SRM), especially in harsh environments. It also increases the complexity of the system. Therefore, the research on sensorless control has become one of the hot spots in recent years. Comparing with the existing sensorless control technology, the new method exploring the sensorless control of double-sided linear switched reluctance motor (DLSRM) shows the following advantages:1)high accuracy , and 2) good practicability. Based on the new proposed method, the DLSRM speed controller is augmented with the peak current method and the voltage chopping closed-loop speed control. Moreover, the winding resistance in the equation is corrected according to the integral flux linkage when the phase current is zero. The accuracy and feasibility of the simplified flux linkage method in estimating the position of the DLSRM is verified.
