Robust Adaptive Algorithms for Reconfigurable Flight Control Systems

Abstract

The objective of the project was to develop adaptive algorithms for application to reconfigurable flight control. An emphasis of the research was on robustness issues related to unmodelled dynamics and actuator saturation. Areas of investigation included: (1) the development of real time parameter identification algorithms for situations where the information content of the data varies significantly over time; (2) the incorporation of integral compensation in adaptive control algorithms with bias cancellation capabilities; and (3) the design of command limiting methods for the alleviation of problems associated with actuator saturation. The results showed that relatively simple multivariable adaptive control algorithms could be designed that were effective in providing flight control reconfiguration over a wide range of flight conditions. A detailed fighter aircraft model was used to evaluate the performance of the reconfigurable control laws in simulations.
