Acceleration Autopilot Design for Portable Missile Based on PDLF-LPV Method
The LPV acceleration autopilot is designed for the portable missile. Since the initial speed of the missile is slow, and the dynamic coefficients vary with time quickly, the LPV control method based on the Parameter Dependent Quadratic Lyapunov Function (PDLF-LPV) is applied to design the acceleration autopilot. During the design process, the LPV reference model is utilized to guarantee the rationality of the autopilot performance index, and the problem that unrealizable rudder deflection command is required by the autopilot can be avoided. Compared with the autopilot designed by the LPV control method based on the single quadratic Lyapunov function (SQLF-LPV), the influence of the variation rate of the scheduling parameter on the autopilot performance is analyzed. Step response simulation and square-wave tracking simulation are made to verify the effectiveness and the robustness of the autopilot designed by PDLF-LPV method.
