Motion control in endurance testing of electric window-lift gear motors

To make the durability performance test of car window motors more closely resemble the actual state of use, an environment durability test method for car window motors based on position control is proposed, which derived from the distributed car window motor durability comprehensive performance testing apparatus developed in the laboratory. Utilizing a torque motor as the actuator, position signals and configuration parameters are set through upper and lower computer communication. The lower computer employs the LQR (Linear Quadratic Regulator) algorithm to adjust the controller parameters for position control. Simulation verification experiments demonstrate that the system responds quickly, with the testing's positioning accuracy controlled within ±2°. Simultaneously, based on random position control, the testing and control device can meet various motor durability test schemes, enhancing testing efficiency.
