Free time and mixed constrained optimal control problems
(2010-12-01)
We consider free time optimal control problems with pointwise set control constraints u(t) ∈ U(t). Here we derive necessary conditions of optimality for those problem where the set U(t) is defined by equality and inequality ...
Using serial bluetooth converters as a sensor link in networked control systems
(2011-12-01)
Networked control systems (NCS) are distributed control system in which sensors, actuators and controllers are physically separated and connected through communication networks. NCS represent the evolution of networked ...
Robust control applied to power flow control in single-phase inverter with LCL filter, using droop control and D-stability
(2012-12-01)
This paper proposes a new methodology to control the power flow between a distributed generator (DG) and the electrical power distribution grid. It is used the droop voltage control to manage the active and reactive power. ...
New approach of induction machine drive using an adaptive digital PID controller with gain planning based on artificial neural networks
(1999-12-01)
The present work introduces a new strategy of induction machines speed adjustment using an adaptive PID (Proportional Integral Derivative) digital controller with gain planning based on the artificial neural networks. This ...
A maximum principle for constrained infinite horizon dynamic control systems
(2011-12-01)
This article presents and discusses a maximum principle for infinite horizon constrained optimal control problems with a cost functional depending on the state at the final time. The main feature of these optimality ...
Evaluating serial ZigBee devices for application in wireless networked control systems
(2012-12-01)
Networked control systems (NCS) are distributed control system where the sensors, actuators and controllers are physically separated and connected through communication networks. NCS represent the evolution of networked ...
A maximum principle for infinite time asymptotically stable impulsive dynamic control systems
(2010-12-01)
We consider an infinite horizon optimal impulsive control problems for which a given cost function is minimized by choosing control strategies driving the state to a point in a given closed set C ∞. We present necessary ...
A multiagent architecture for supervisory and control system
(2008-12-01)
Supervising and controlling the many processes involved in petroleum production is both dangerous and complex. Herein, we propose a multiagent supervisory and control system for handle continuous processes like those in ...
Discrete-time sliding mode control of input-delay systems applied on a power generation system
(2006-12-01)
This paper presents two discrete sliding mode control (SMC) design. The first one is a discrete-time SMC design that doesn't take into account the time-delay. The second one is a discrete-time SMC design, which takes in ...
Optimal linear and nonlinear control design for chaotic systems
(2005-12-01)
In this work, the linear and nonlinear feedback control techniques for chaotic systems were been considered. The optimal nonlinear control design problem has been resolved by using Dynamic Programming that reduced this ...
