Research on Control Method of Substation Intelligent Inspection Robot

Aiming at the problem that the identification of the initial position of the motor rotor by the positioning method is likely to cause a fixed position deviation, resulting in an inaccurate initial position and affecting the control accuracy of the inspection robot, a motor rotor position control method that integrates the maximum current method and the encoder accumulated value method is proposed. The precise positioning of the rotor position of the motor by the servo control system. Taking the substation inspection robot as the test object, the real error of the control algorithm is analyzed. The test results show that the algorithm error is less than 6° electrical angle, and has good speed regulation performance, which can effectively prevent the motor from stalling, out of step and overstepping, ensuring the smooth operation of the robot and meeting the requirements for stability and reliability.
