摘要： A system includes a permanent magnet motor having a rotor and a stator. The rotor and the stator have a configuration that causes the motor to generate a back-electromagnetic force (EMF) waveform that is substantially sinusoidal. The system also includes a motor controller having a sliding-mode observer configured to identify the back-EMF waveform and a position observer configured to estimate at least one characteristic of the motor using the identified back-EMF waveform. The stator may include multiple teeth projecting towards the rotor and multiple conductive windings, where each conductive winding is wound around a single tooth. The rotor may include multiple magnetic poles, where each magnetic pole has a span of about 60° or less. The sliding-mode observer may be configured to receive current measurements associated with three-phase signals and voltage commands generated by the motor controller. The position observer may include a proportional-integral (PI) regulator.

摘要： An electric motor is controlled using a feedback signal that includes an error between the measured current and the estimated current determined using the measured current, the measured voltage, and a model of the motor. A feedback gain is determined as an error function of a feedback signal and a speed of the motor is estimated using a product of the feedback gain and the feedback signal. The voltage of the motor is determined using a difference between the estimated speed of the motor and a reference speed of the motor and the motor us controlled using the determined voltage.

摘要： The present invention provides a simple, robust, and universal position observer for use with sensorless synchronous machines. The observer may be implemented using an equivalent EMF model of a synchronous machine or, alternately, using a sliding mode controller based on the equivalent EMF model of the synchronous machine. The observer may be used on any type of synchronous machine, including salient or non-salient pole machines such as a permanent magnet, interior permanent magnet, wound rotor, or reluctance synchronous machine. The observer provides low sensitivity to parameter variations and disturbances or transient conditions in the machine. In addition, no knowledge of speed is required as an input to the observer and an estimated position may be calculated using a subset of the machine parameters.
