Recently the adaptive mixing control (AMC) approach has been applied to an airbreathing hypersonic flight vehicle (AHFV) model, and simulation results demonstrate that this adaptive scheme may be capable of improving performance when compared to a non-adaptive mixed-mu design with similar objectives. In this note, the analysis of this AMC scheme's stability and robustness properties is presented,...
We apply the adaptive mixing control approach to a simple example, presenting concepts of the design and analysis of these schemes in a pedagogical manner. Unique to deterministic multiple model adaptive control schemes, adaptive mixing control does not switch discontinuously among candidate controllers. Continuous ??mixing?? is possible because the multicontroller is constructed by controller interpolation...
Continuous time decentralized indirect adaptive controllers are proposed for a large scale system composed of N interconnected linear subsystems with unknown parameters. Each local adaptive law utilises a normalising signal which is generated using the local input and the outputs of all the subsystems. Sufficient conditions for the closed loop stability of the adaptively controlled large scale system...
The certainty equivalence principle is used to combine a robust adaptive law with a control structure derived from the linear quadratic (LQ) control problem. The resulting adaptive control scheme is applicable to minimum and non-minimum phase continuous-time plants and is robust with respect to unmodeled dynamics and bounded disturbances. The computational complexity of the continuous-time adaptive...
