Abstract:

On vehicle-mounted moving base, the vehicle tire and suspension’s elastic deformation will play a role in disturbances in rapid servo control system. Through the analysis of the influence of vehicle disturbance for motor control system, this article determines the key technology of high precision servo system on the moving base is to measure the cars chassis suspension system natural vibration frequency, according to the result of the disturbance data to design low-pass filter and servo control strategy, and the simulation of the servo system is also carried out. In the end, as an example, the above research results are applied to a certain motor servo system installed on moving base. The final test results show that the servo system in this paper, the filter and effectively suppresses the bodywork disturbance servo control strategy for ac servo motor, the influence of control precision meet the system requirements.
