Switched control design with guaranteed cost for uncertain nonlinear systems subject to actuator saturation
(2020-01-01)
This manuscript proposes a robust switched controller design with minimization of an upper bound of a quadratic performance index (guaranteed cost) related to the system output for a class of uncertain nonlinear systems ...
On Nonlinear Dynamics and Control of A Particular Portal Frame Foundation Model, Excited by a Non-Ideal Motor
(2003-12-08)
The nonlinear dynamic response and a nonlinear control method of a particular portal frame foundation for an unbalanced rotating machine with limited power (non-ideal motor) are examined. Numerical simulations are performed ...
On optimal control of a nonlinear robotic mechanism using the saturation phenomenon
(2015-01-01)
In this paper a robotic arm is modelled by a double pendulum excited in its base by a DC motor of limited power via crank mechanism and elastic connector. In the mathematical model, a chaotic motion was identified for a ...
On nonlinear dynamics and control of a robotic arm with chaos
(E D P Sciences, 2014-01-01)
In this paper a robotic arm is modelled by a double pendulum excited in its base by a DC motor of limited power via crank mechanism and elastic connector. In the mathematical model, a chaotic motion was identified, for a ...
Smoothing switched control for uncertain T-S fuzzy systems with unknown membership functions, actuator saturation and disturbance
(Ieee, 2016-01-01)
This paper proposes conditions that ensure local ultimate bounded stability for nonlinear systems constrained to a region of operation, subject to actuator saturation and persistent norm-bounded disturbance. The nonlinear ...

Using saturation phenomenon to improve energy harvesting in a portal frame platform with passive control by a pendulum
(2016-01-01)
A new model of energy harvester based on a simple portal frame structure subjected to saturation phenomenon is presented. Energy is collected via a piezoelectric device whose nonlinearities are considered in the mathematical ...
