Abstract


Preparations for military struggle in the course of the future, an urgent task is to the air defense and antimissile. Multiple rocket launcher has its unique advantages for the air defense and antimissile because of fire heavy, flexible, low prices. In this paper, a servo tracking system of self-defense rocket launcher is studied, in order to improve the ability of the air defense rocket to capture the target, the key is to respond moving target rapidly, point out the target location with less overshoot. In this paper, due to a large parameter variations, poor load characteristics, the strong impact of disturbance torque in the servo tracking of the self-defense rocket system, an improved fuzzy PID control algorithm with thorough analyzing convention two-dimensional fuzzy controller is applied to servo tracking system of the independent anti-aircraft rockets and its the concrete realization is studied in depth and detail; theoretical analysis and experimental results show that there is better adaptive ability and robustness to ensure the accuracy of target tracking. On account of the ability of the infrared imaging to obtain high-resolution target image in the night and under adverse weather conditions, thus this paper, a nonlinear filter with infrared tracking technology is advanced for the self-defense rocket to track the target,experiments show that this algorithm can track the infrared target effectively and accurately.Finally, the overall proposal of the servo tracking system of anti-aircraft rockets is designed, focus on the control system being designed in detail as well as the concrete realization of control algorithm; then the prototype of self-defense rocket as the experimental platform to carry out the classic PID control and adaptive fuzzy PID control experiment, which proved adaptive fuzzy PID algorithm with some value in engineering is better to improve the system performance.
