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/H2 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 H2 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.
