Missile control systems design based on model tracking GSVSC theory

Considering the over-load tracking problem of the pitch channel control system for STT missile, a new control algorithm is proposed based on model tracking global sliding mode variable structure control (GSVSC) theory. Combining the mathematical model of STT missile pitch plane, its tracking error model is presented together with the criteria for model complete tracking. According to the dynamic and stability index, the sliding mode parameter matrix and the global sliding mode factor are designed respectively. Lastly, the stability of the algorithm is analyzed. Simulation results show that the proposed approach has good dynamic properties and strong robustness.
