One output shaft of the DCmotor is connected with an optical encoder, the other output shaft is connected with a flywheel inertial load , the output shaft of the flywheel inertial load l is connected with a torque sensor through a coupling, and the signal output ends of the optical encoder and the torque sensor are respectively connected with a control system. The control system is composed of contour controller and motor.The whole controller is based on the disturbance compensation. The sliding mode controller is used in the controller design to minimize the tracking error as its adjustment function so that better control efficiency can be obtained. The device and the control system thereof not only have high control accuracy, but also have simple and compact structure and good use effect.

Description

technical field [0001] The invention relates to the field of motor controllers, in particular to a DC motor servo control method based on a robust disturbance compensation scheme. Background technique [0002] DC motors are widely used in a variety of different applications such as hard disk drives, machine tools, robotic arm drives, and many more. However, friction can cause steady-state errors and limit cycles, which degrade the performance of DC servo motors. Therefore, it is necessary to develop effective friction compensation technology and improve the performance of servo system. Although model-based compensation schemes can effectively compensate for the effects of friction, their use requires precise knowledge of the friction model and its parameters. Furthermore, the nature of the frictional effect may change due to environmental factors such as temperature, lubrication conditions, etc. Therefore, model-based compensation schemes must rely on offline or online re...
