Design and implementation are studied for a neural-network-based predictive controller meant to govern the dynamics of non-linear processes. The advantages of using neural networks for modeling non-linear processes are shown together with the construction of neural predictors. The resulting implementation of the neural predictive controller is able to(More)

In this paper we develop a priori stabilization conditions for infinity norm based hybrid MPC in the terminal cost and constraint set fashion. Closed-loop stability is achieved using infinity norm inequalities that guarantee that the value function corresponding to the MPC cost is a Lyapunov function of the controlled system. We show that Lyapunov(More)
The componentwise asymptotic stability (CWAS) and componentwise exponential asymptotic stability (CWEAS), introduced and characterized in previous works, are used to define componentwise stabilizability / detectability and componentwise exponential stabilizability / detectability for both discrete-and continuous-time linear systems. The approach brings a(More)
New results of qualitative analysis are presented for a class of neural networks (Hopfield-type), representing a refinement in the interpretation of their behaviour. The main instrument of this analysis consists in the individual monitoring of the state-trajectories by considering time-dependent rectangular sets that are forward invariant with respect to(More)
For Popov's frequency-domain inequality a general solution is constructed in L 2 , which relies on the strict positive realness of a generating function. This solution allows revealing time-domain properties, equivalent to the fulfilment of Popov's inequality in the frequency-domain. Particular aspects occurring in the dynamics of the linear subsystem(More)
