Research And Simulation On Cross-coupled Control Approach For Servo Systems Of Multi Artillery

Artillery is a powerful weapon in the war. It is very urgent to improve the efficiency and accuracy of artillery to meet the requirement of contemporary information war. Salvoes of a group of artillery are the most used striking means in the battlefield. Many factors, such as the dynamic characteristics and random disturbance, can raise the positioning errors and synchronization errors, which will inevitably reduce the positioning accuracy of artillery.Aimed to solve this problem, this paper has studied in detail the structure of servo systems and analyzed some control schemes which are widely used nowadays in many fields. Two kinds of disturbances such as the random noise disturbance and the parameter variation between artillery servo loops have been taken into consideration. To compensate errors induced by disturbances, a cross-coupled control strategy has been developed to shape the controller for synchronization of two artilleries. This controller is stable and easy to implement; moreover it is more robust.The simulation results have demonstrated that the error between synchronized artilleries has been decreased significantly by 25%. A satisfactory agreement between artilleries has been achieved. The artilleries can be expected a better performance in battlefields once equipped with the controller. Therefore the approach is a valuable reference for the control of a group of artillery.By applying the approach of cross-coupled control method, the structure of servo system will be improved and thus the performance of artillery will be enhanced. Meanwhile this approach is promising in other fields like the control of radar or missile and the industrial control practice.
