The Laser Beam Riding Guided Anti-tank Missile Control System Design And Simulation

In this thesis, the design of guidance and control system for the laser beam rider guidance anti-tank missile is studied. Based on some characteristics of this missile, the thesis computes the aero-force of the new designed missile and establishes the model.Based on some previous work, the simulation results show that Model-following Variable Structure Control Theory improves the performance of the control system. So, Variable Structure Control Theory is used in angle stabilization of roll, and Model-following Variable Structure Control Theory is used in acceleration stabilization of pitch and yaw.A kind of series connection correction network is designed, which can obtain high accuracy of guidance and stability and can greatly restrain the non-linear effect caused by laser coding.Also, a set of six-degree simulation system is established, which consists of all kinds of non-ideal factors, disturbance and movement model of targets. According to the results by this simulation system, respected accuracy and stability can be acquired, as proved that the design of the control system is successful. The Partial Model-following Variable Structure control theory and the six-degree simulation system used in this thesis will be widely used in design of control system.
