Circuit Implementation of a Modified Chaotic System with Hyperbolic Sine Nonlinearities Using Bi-Color LED

Technologies, 2021
In this paper, a chaotic three dimansional dynamical system is proposed, that is a modification of the system in Volos et al. (2017). The new system has two hyperbolic sine nonlinear terms, as opposed to the original system that only included one, in ...

Nonlinear optimal controls

Journal of Computer and System Sciences, 1970
In this paper we state a necessary condition for optimality for unconstrained controls. For certain systems a constructive proof is given showing the existence of controls satisfying this condition.

Hard constraints in control state variables of multivariable nonlinear processes resolved by elementary nonlinear decoupling [PDF]

Modeling, Identification and Control, 1998
A model based control strategy for nonlinear multivariable processes having hard constraints on both control and state variables, is derived based upon the concept of Elementary Nonlinear Decoupling (END). In END a property space is defined which has the
