Switching Adaptive Control of Time-Varying Plants (2008)
We study the problem of adaptively stabilizing time-varying plants using supervisory control, which employs multiple controllers and a supervisory unit that orchestrates switching among the...
Nonlinear norm-observability notions and stability of switched systems (2005)
Hespanha, Joao P, Liberzon, D, Angeli, D, Sontag, E D
This paper proposes several definitions of "norm-observability" for nonlinear systems and explores relationships among them. These observability properties involve the existence of a bound on the...
Overcoming the limitations of adaptive control by means of logic-based switching (2003)
Hespanha, Joao P, Liberzon, D, Morse, A S
In this paper we describe a framework for deterministic adaptive control which involves logic-based switching among a family of candidate controllers. We compare it with more conventional adaptive...
Hysteresis-based switching algorithms for supervisory control of uncertain systems (2003)
Hespanha, Joao P, Liberzon, D, Morse, A S
We address the problem of controlling a linear system with unknown parameters ranging over a continuum by means of switching among a finite family of candidate controllers. We present a new...
