For solving problems of self-propelled artillery training such as high practical training cost, high difficulties for organization, and hard for assessment, use semi-physical simulation turret operation training method and subsection and intelligent PID control of AC servo system strategy to research on servo control system of self-propelled artillery simulation trainer. The method detailed describes the function, composition, parameter calculation method and control strategy of simulation trainer servo system. The application results show that the operation mode of simulation trainer is the same as the practical operation, the technology and performance technology of servo system can satisfy the requirements of daily training and examine. The technology method has certain guiding significance for carrying out similar simulation training platform.
