Research On The High Accuracy Control For The Shipboard Artillery Shooting Simulation Device

Electro-hydraulic servo control system is equipped with fast response, high control precision, and large output power, etc. Therefore, the research about the hydraulic servo system with large inertia load which is 600 KN is carried out to archieve the high performance control for the device.Based on the shipboard artillery shooting simulation device, the hydraulic servo system with large inertia and high speed is taken as the research object. According to the performance indexes of the shipboard artillery shooting simulation device, the type selection and design for the core element and design and checking for the control system, are accomplished for the hydraulic servo system. And the hydraulic servo system with large inertia is analyzed in detail to achieve the structure features and technical parameters. According to actual the hydraulic servo system, based on the principle of the hydraulic control system, the mathematical model of the asymmetric valve control asymmetric cylinder and the dynamic mathematical model of valve core, etc, are established. Then its simplified open-loop transfer function of the hydraulic system can be easily achieved. And according to the mathematical model, partition variable parameter PID control method is proposed which is based on the velocity and acceleration feed-forward. Then AMESim and Matlab/Simulink are used to build the joint simulation model of the hydraulic servo system for the simulation analysis. Then with friendly interface, good user experience, strong operability, high security and good reliability as the design objective, the shooting simulation software which is equipped with feasible, safe and reliable, friendly interface, is provided for the users. Finally in view of the simulation results, the partition variable parameter PID control algorithm which is based on the bang-bang control and integral separation control is adopted in the repeated debug test for hydraulic servo system. The results show that this control strategy for the high accuracy position control of the servo system with high speed and large inertia proposed in this research can achieve good control effect.
