Saturation nonlinearities are ubiquitous in engineering systems. In control systems, every
physical actuator or sensor is subject to saturation owing to its maximum and minimum …

In assessing system performance, the control engineer armed with linear analysis and
design techniques soon encounters a fundamental nonlinear problem that threatens the …

As we discussed in Chapter 5, in the implementation of linear digital filters, signals are
usuMly represented and processed in a finite wordlength format. Therefore, such …

The paper considers the problem of steering the state of a linear time-varying system to the
origin when the control is subject to magnitude constraints. Necessary and sufficient …

The book gives a novel treatment of recent advances on constrained control problems with
emphasis on the controllability, reachability of dynamical discrete-time systems. The new …

We present some necessary and sufficient conditions for null controllability for a class of
general linear evolution equations on a Banach space with constraints on the control space …

The linear state equation ̇ x (t)= A (t) x (t)+ B (t) u (t) is said to be locally Ω-null controllabe if,
for every initial condition x 0 in some neighborhood of the origin, there exists a measurable …

This volume develops a systematic study of time-dependent control processes. The basic
problem of null controllability of linear systems is first considered. Using methods of ergodic …

Consider the problem of null-controllability for a linear non-autonomous system of the form ̇
x (t)= A (t) x (t)+ B (t) u (t), x (t) ε X, u (t) ε Ω ⊂ U, where X and U are Banach spaces, A (t) and …

The problem of finding the minimum input norm required to bring a dynamical system from
an arbitrary initial state to a given end-point constraint set under specified state constraints …
