Nonlinear H Flight Control System (FCS) Design for Advanced Aircraft

Advanced aircraft are required to perform large amplitude maneuvers and high precision tracking in the presence of disturbances, uncertainties, nonlinearities, and component faults. The recently emerging nonlinear H control approach is proposed here to meet the ever stringent mission requirements on advanced aircraft. Our approach features the following innovations: 1) by incorporating the nonlinear dynamics into the design process, a nonlinear H flight control system design approach in the continuous time domain is presented; 2) for performing the computer control of aircraft, a nonlinear H controller design algorithm for continuous-time systems with sampled measurements is developed; 3) a nonlinear H controller design algorithm for general nonlinear systems is proposed. These innovations aim at achieving a flight control system design with a high level of accuracy, extended flight envelop, robustness, and reliability in presence of disturbances and uncertainties. system design approach in the continuous time domain is present;
