Research and Application of Optimal Nonlinear Control Theory in Missile Control

In this paper, the phase path motion equation is derived by using phase plane method firstly. In the traditional control methods the primary factors which effects control precision are analyzed and its solutions are proposed. Furthermore, according to the practice characteristics, the control law is designed by using the quadratic switch line method and optimal control theory. The optimal control problem with complex index combining shorter time and fewer fuel is also discussed. Simulation results show that the designed method possesses advantages such as simplicity, reliability and good perspective of engineering application.
