Asymptotic stability of systems with saturation constraints

In the present paper we establish new sufficient conditions for the global asymptotic stability of linear systems operating on the unit hypercube in Rⁿ and of linear systems with partial state saturation constraints. We also determine a set of necessary and sufficient conditions for the global asymptotic stability of second order linear systems with saturation constraints on both states using the above results. Systems of the type considered herein are widely used in several areas of application, including control systems, signal processing, and artificial neural networks
