Title STUDY ON MODELLING AND SIMULATION OF GUN SERVO SYSTEMS
Abstract This article chooses the servo system of guns as a subject and analyses the parts of the system, including the operation theory and performance of the digital controller and power part. Based on the operation theory, this article designed a model about this gun servo system with the idea of models. Meanwhile, the paper explains the two different control theories; those are the square root control and PID control. In the end, the simulation is done in the SIMULINK, the result is analyzed. Through the process, the system controller data is changed. And finally comes out of an ideal result. The simulation result shows the movement and static character. The result proves that this system satisfies required needs. This article can be the proof for adjusting gun system data. It can also serves as reference for designing new kind of gun servo systems.
