Abstract:The deployable structure of the antenna proposes to adopt a PMSM (permanent magnet synchronous motor) to improve reliability. The traditional control method of PMSM requires mechanical sensors, which brings problems such as reduced reliability. The implementation of the high-frequency signal injection method is simple and flexible, and the method is not sensitive to motor parameters changes, so it has become the preferred method. In this paper, a sensorless control algorithm for the deployable structure of the… Show more
