Optimal control in a noisy system
(AMER INST PHYSICS, 2008-07-21)
We describe a simple method to control a known unstable periodic orbit UPO in the presence of
noise. The strategy is based on regarding the control method as an optimization problem, which
allows us to calculate a ...

Sensorless Adaptive Voltage Control for Classical DC-DC Converters Feeding Unknown Loads: A Generalized PI Passivity-Based Approach
(Cartagena de Indias, 2021-09-24)
The problem of voltage regulation in unknown constant resistive loads is addressed in this paper from the nonlinear control point of view for second-order DC-DC converters. The converters’ topologies analyzed are: (i) buck ...
Discrete-Inverse Optimal Control Applied to the Ball and Beam Dynamical System: A Passivity-Based Control Approach
(Cartagena de Indias, 2020-08-14)
This express brief deals with the problem of the state variables regulation in the ball and beam system by applying the discrete-inverse optimal control approach. The ball and beam system model is defined by a set of ...
Global Optimal Stabilization of MT-HVDC Systems: Inverse Optimal Control Approach
(Cartagena de Indias, 2021-11-17)
The stabilization problem of multi-terminal high-voltage direct current (MT-HVDC) systems feeding constant power loads is addressed in this paper using an inverse optimal control (IOC). A hierarchical control structure ...
Adaptive control for second-order DC-DC converters: PBC approach
(Cartagena de Indias, 2021)
This chapter deals with the design of a passivity-based controller for DC-DC converters by using a general representation for second-order converters, that is, buck, boost, buck-boost, and noninverting buck-boost converters. ...
SCES Integration in Power Grids: A PBC Approach under abc, αβ0 and dq0 Reference Frames
(Institute of Electrical and Electronics Engineers Inc., 2018)
This paper presents an integration of three-phase supercapacitor energy storage (SCES) in power grids via passivity-based control (PBC) theory under different reference frames. The SCES systems have the possibility to ...
