Simulation Research For The Control System Of Terminal Guided Mortar Projectile

This article elaborates the control principle and working process of the terminalguided mortar projectile, analyzes its aerodynamic layout and puts forwards using theduck type layout control mode. The advantages and disadvantages of proportionalguidance law,three point method, parallel approaching method are analyzed, andthe proportional guidance law is proposed as the guidance law of the guidance system,in the addition, to improve the accuracy of the terminal guided mortar projectile,thenonlinear predictive filter algorithm is adopted to filter the signals of guidance;Terminal guided mortar projectile space motion model is established, and its controlsystem use the sub-channel control design and controlled by PID correction network toimprove the system performance; The MATLAB/Simulink software tool is used tosimulate the filtering part of its guidance, guidance law, servo control and sub-channelcontrol system, verify and improve the control performance of the system, thesimulation results show that terminal guided mortar projectile greatly improves theaccuracy of the mortar projectile.
