Robust LPV missile autopilot design with parameter dependent performance

In this paper the application of linear parameter varying (LPV) control with parameter dependent performance to an advanced missile is presented. The existing LPV control techniques are based on robust control theory using a uniform upper performance bound over the whole parameter space. So the controller performance might be limited by the worst-case parameter variations. To deal with this problem, the constant performance bound is generalized as functions of the scheduling parameters for the general LPV systems. The controller synthesis conditions are reformulated as linear matrix inequalities (LMIs) which can be solved efficiently by the convex optimization algorithms. The missile autopilot design was used to illustrate this systematic approach.
