Abstract

A study was conducted to demonstrate robust aeroelastic control of lifting surfaces with uncertainty through a multi-objective state-feedback control design. The study demonstrated that the multi-objective robust design referred to the mixed H /H 2 problem and corresponded to the robust stability and nominal performance for state-feedback and output-feedback cases. The study also demonstrated the implementation of a multi-objective state-feedback control methodology for the control of a wing section. It was found that the H performance was favorable for enforcing robustness to model uncertainty and to express frequency domain specifications. It was demonstrated that the H 2 performance was useful for handling stochastic aspects, such as measurement noise and random disturbance. The investigations also revealed that the multi-objective design allows for a flexible and accurate specification of the desirable closed-loop behavior.
