Abstract:
The linear, parameter varying (LPV) modeling and autopilot design for a high-agile surface-to-air missile is presented. Missile autopilot design poses a challenging task, because a wide flight envelope needs to be covered by the resulting controller while fulfilling robust stability and performance requirements at the same time. Furthermore, the dynamic behavior of the missile is highly nonlinear and dependent on rapidly changing variables like the Mach number and incidence angle. For the example of a dual pulse missile presented here relevant changes in mass and center of gravity, respectively, have an additional large influence on the dynamics. In this paper a quasi-LPV model is derived, which also takes these influences into account and thus approximates the nonlinear missile behavior over the entire flight envelope. The choice of scheduling variables is discussed and the quality of the approximation is examined. Based on the developed quasi-LPV model, an exemplary LPV autopilot design is presented and the robustness of the closed-loop system is assessed. The autopilot performance is demonstrated within a high-fidelity simulation environment.
