Abstract	:	Neural network-based adaptive output feedback approaches that augment a linearcontrol design are described in this thesis, and emphasis is placed on their real-time implementationwith .exible structural systems. Two di.erent control architectures that arerobust to parametric uncertainties and unmodelled dynamics are presented. A key featureof these approaches is that the order of the system need not be known. The unmodellede.ects can consist of minimum phase internal dynamics of the system together with externaldisturbance process acting on the system. Within this context, adaptive compensation forexternal disturbances is addressed.In the .rst approach, internal model-following control, augmenting elements are designedusing feedback inversion. The e.ect of an actuator limit is treated using control hedging, andthe e.ect of other actuation nonlinearities, such as dead zone and backlash, is mitigated bya disturbance observer-based control design. The e.ectiveness of the approach is illustratedthrough simulation and experimental testing with a three-..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
