Adaptive Control of a Class of Time-Delay Systems

摘要: The control of physical systems in the presence time-delays becomes particularly challenging when parametric uncertainties are present. To cope with these ubiquitous uncertainties, we propose an adaptive controller this paper that can accommodate both a time-delay and uncertainties. includes a) architecture is based on plant relative degree rather than order, b) integral implementation well known Posicast Controller so as to unstable plants, c) high-order tuners for parameter adaptation, d) Lyapunov-Krasvoskii functional allows stabilization. shown be semi-global r result asymptotic tracking. implications explored context combustion through simulation studies. Robustness properties briefly discussed.
