Enforcing Constraints in Industrial Control Systems: Command Governor Tools (2007)
D. Angeli, A. Casavola, E. Mosca
The problem of constrained control of linear plants is addressed. Some algorithms are proposed that ensure constraints fulfillment and set-point tracking through a non-linear filtering action...
Uniform global asymptotic stability of differential inclusions (2007)
D. Angeli, B. Ingalls, E. D. Sontag, Y. Wang
Stability of differential inclusions defined by locally Lipschitz compact valued maps is addressed. It is shown that if such a differential inclusion is globally asymptotically stable, then in fact...
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...
Separation principles for input-output and integral-input to state stability (2004)
D. Angeli, B. Ingalls, E. D. Sontag, Y. Wang
Abstract. We present new characterizations of input-output-to-state stability. This is a notion of detectability formulated in the ISS framework. Equivalent properties are presented in terms of...

Separation Principles for Input-Output and Integral-Input-to-State Stability (2004)
D. Angeli, B. Ingalls, E. D. Sontag, Y. Wang
We present new characterizations of input-output-to-state stability. This is a notion of detectability formulated in the ISS (input-to-state stability) framework. Equivalent properties are presented...
Uniform Global Asymptotic Stability of Differential Inclusions (2004)
D. Angeli, B. Ingalls, E. D. Sontag, Y. Wang
Stability of di#erential inclusions defined by locally Lipschitz compact valued mappings is considered. It is shown that if such a di#erential inclusion is globally asymptotically stable, then, in...
D. Angeli, A. Casavola, M. Giannelli, E. Mosca
A receding-horizon strategy is presented for set-point tracking and global stabilization of asymptotically null controllable plants in the presence of actuators with position and rate limiting...
A Small-Gain Theorem for Almost Global Convergence of Monotone Systems
D. Angeli, P. De Leenheer, E.D. Sontag
A small-gain theorem is presented for almost global stability of monotone control systems which are open-loop almost globally stable, when constant inputs are applied. The theorem assumes...
