Robust flight control using parameterized compensator

The authors outline a design method for achieving the desired robustness and performance requirements of a flight control system. By using the U-parameter robust compensator design method, the compensator and the closed-loop transfer function can be formulated with free parameters, Moreover, based on a model reference approach, a simple method is introduced to minimize the H²-norm of the error between the designed closed-loop transfer function and the reference model to determine the free parameters of the compensator such that the desired robustness and performance requirements can both be met. Simulation results show that the proposed method can achieve good robustness and performance for the flight control system
