The methods of nonlinear dynamic inversion and structured singular value synthesis are combined to address both the nonlinearity and robustness problems of flight at poststall maneuver conditions.

The structured singular value analysis of edge polynomials with variable length;

Decentralized Robust Control Theory and Its Application Based on Structured Singular Value Approach;

It incorporates organically the flight test data and the flutter theory model by the structured singular value theories,to process the flutter boundary estimate.

Then we give out the three research methods: Kharitonov interval theory, structured singular value theory and H ∞ control theory.

The one main content of this thesis is to propose a new method to design H∞loop shaping robust controller by choosing weighting function, and the second content is to discuss the relation of weighting functions between H∞loop shaping controller andμloop shaping controller, which is based on structured singularμand loop shaping.

Other factors such as thrust limitation,maximum thrust change rate of thrust,maximum slew rate of thrusters,forbidden sector for the thrust direction angle and singular configuration avoidance are also taken into consideratio.
