Methods of Ensuring Invariance with Respect to External Disturbances: Overview and New Advances

Mathematics, 2021
In this paper, we carry out a demonstration and comparative analysis of known methods of the synthesis of various control laws ensuring the invariance of the output (controlled) variable with respect to external disturbances under various assumptions ...

Guaranteed robustness properties of multivariable, nonlinear, stochastic optimal regulators [PDF]

, 1983
The robustness of optimal regulators for nonlinear, deterministic and stochastic, multi-input dynamical systems is studied under the assumption that all state variables can be measured.

Nonlinear Dynamic Model-Based Adaptive Control of a Solenoid-Valve System

Journal of Control Science and Engineering, 2012
In this paper, a nonlinear model-based adaptive control approach is proposed for a solenoid-valve system. The challenge is that solenoids and butterfly valves have uncertainties in multiple parameters in the nonlinear model; various kinds of physical ...

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.

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 ...

Nonparametric nonlinear model predictive control [PDF]

, 2004
Model Predictive Control (MPC) has recently found wide acceptance in industrial applications, but its potential has been much impeded by linear models due to the lack of a similarly accepted nonlinear modeling or databased technique.
