Abstract

We present a design of an autopilot for a Bank-to-Turn asymmetric missile. The autopilot is synthesised using a method based on a linear parameter varying model of the missile, and because of significant cross-couplings in the different channels a multivariable design is considered. In the paper, attention is first focussed on the development of an LPV model of the missile. The choice of the scheduling variables and the reliability of the model are also discussed. Then a multivariable controller is designed using H_∞ loop-shaping extended to LPV polytopic plants. The performance of the control law is evaluated through simulations at various frozen points of the LPV model.
