Simulation Model Of Semi-active Laser Guidance And Control System For Fast Moving Target

With the continuous improvement of the guidance precision to the missile,the improvement of the air defense missile's performance is imminent.Semi-active aser guidance system not only has good guidance accuracy but also has good anti-interference ability.Therefore, the semi-active laser guided system is applied in the air defense missile,which can improve the hit rate of the missile.Because the target is running fast, this paper makes a research on how to capture the target and track the target.The following aspects is included in this paper:First, the specific content of the model is established based on the spatial motion of interceptor missile through literature research and analysis.Second, the guidance law and control system are designed with the aim of stability and rapidity. And through the parameter adaptive tuning algorithm, the system is calibrated.Third, the interception efficiency of the control system is simulated and evaluated. And it is concluded that the maximum overloadof missile is required under different missile guidance parameters.Finally, the aerodynamic shape of missile is designed and the simulation is carried out.The aerodynamic parameters of the missile are obtained,and the maximum overload of the missile can be calculated. Verify that the control system is feasible.
