Strong exponential stability of switched impulsive systems with mode-constrained switching
Alexis J. Vallarella, José Luis Mancilla-Aguilar, Hernan Haimovich
Strong stability, defined by bounds that decay not only over time but also with the number of impulses, has been established as a requirement to ensure robustness properties for im…
On the stability of nonlinear sampled-data systems and their continuous-time limits
Alexis J. Vallarella, Hernan Haimovich
This work deals with the stability analysis of nonlinear sampled-data systems under nonuniform sampling. It establishes novel relationships between the stability property of the ex…
Semiglobal exponential input-to-state stability of sampled-data systems based on approximate discrete-time models
Alexis J. Vallarella, Paula Cardone, Hernan Haimovich
Exact discrete-time models of nonlinear systems are difficult or impossible to obtain, and hence approximate models may be employed for control design. Most existing results provid…
Characterization of semiglobal stability properties for discrete-time models of non-uniformly sampled nonlinear systems
Alexis J. Vallarella, Hernan Haimovich
Discrete-time models of non-uniformly sampled nonlinear systems under zero-order hold relate the next state sample to the current state sample, (constant) input value, and sampling…
State measurement error-to-state stability results based on approximate discrete-time models
A. J. Vallarella, H. Haimovich
Digital controller design for nonlinear systems may be complicated by the fact that an exact discrete-time plant model is not known. One existing approach employs approximate discr…
