Active Nonlinear Feedback Control for Aerospace Systems. Processor
Abstract
Although the theory of linear control systems is highly mature, nonlinear control-system design techniques remain relatively undeveloped. In real-world applications such as vibrations suppression in flexible structures and large angle rigid-body spacecraft maneuvers, nonlinear plants generally require nonlinear controllers, while linear controllers, while linear plants often benefit from the implementation of nonlinear controllers in the presence of structured plant uncertainty, actuator constraints, and nonquadratic performance criteria. This report discusses progress in several areas relating to the role of nonlinearities in feedback control. These area include Lyapunov function theory, chaotic controllers, statistical energy analysis, phase robustness, and optimal nonlinear control theory.
