Computer Robust Control Of Ac Servo System

This paper is based on an artillery servo system which requires high control qualities such as the speeding, accuracy, and stability under hard circumstances like the great variation of the load and the huge changes of the torsion.The main contents of this paper include the hardware design of the AC servo system, software programming and the adjustment of the whole system. The part of the hardware emphasizes on the design of the servo amplifier, and presents the model of the servo system. And considering the uncertain factors that the system may meet during the operation, a H robust control algorithm is employed when devise the controller of the system to compensate disturbances and unmodeled factors of the system. Finally, simulation and experiments are done to test the system's robustness and performance.According to the results of the simulation and experiments, it is known that with the controller which is depended on the H algorithm the system is self-adaptive and has the robust character for the change of the model parameters. And the outside inferences and load variation can be retained effectively.
