Induction machines still dominate in industrial applications, but synchronous reluctance machines (SyRMs) and PM-SyRMs are becoming more popular due to their higher torque density and efficiency. For cost saving reasons, industrial drives are typically required to be sensorless and their start-up process should be quick and easy. Ideally, any unknown AC motor can be plugged into a general-purpose inverter, which first automatically identifies the motor model with minimal user intervention, then configures the control system based on the identified model, and finally runs the motor in an optimal manner. Sensorless induction motor drives with these kind of plug-and-play features have been commercially available for the last 20 years, but suitable methods for SyRMs and PM-SyRMs are just emerging. This presentation discusses the state-of-the-art, challenges, and future trends of sensorless plug-and-play control from the perspective of industrial drives (but many aspects are applicable to traction drives as well).
