Motor observation method and device, electronic equipment and aircraft

The invention provides a motor observation method and device, electronic equipment and an aircraft, and the method comprises the steps: controlling a motor to start through a target controller in a starter under the condition that the motor is determined to be in a static state; when it is determined that the motor is in the first target operation state, switching to a sliding mode variable structure observer; and a sliding mode variable structure observer is adopted to carry out state observation on the motor. According to the method, the target controller in the starter is adopted to control the motor to start, and under the condition that the motor is determined to be in the first target operation state, the starter is switched to the sliding mode variable structure observer to perform state observation on the motor, so that the problem that the motor is observed by using the sliding mode variable structure observer is effectively solved; and when the motor is static, the sliding mode variable structure ob
