Aiming at the problem that the initial position error of the rotor of the permanent magnet synchronous motor identified by the positioning method is large,which affects the control accuracy of the servo control to the per-manent magnet synchronous motor and leads to the large positioning deviation of the substation inspection robot,a rotor initial position identification method based on the maximum current method is proposed and applied to the ser-vo control system of the substation inspection robot.Taking the inspection robot as the test object,the control accura-cy of the improved identification method is verified.The test results show that the error absolute value of the im-proved identification method is less than 5 electrical angle,which can effectively solve the problem of permanent magnet synchronous motor stall,out-of-step and overstep,and has good stability and reliability.
