Minimum energy DP heading control : critical analysis and comparision of different strategies
(Ocean, Offshore and Arctic Engineering DivisionNantes, 2013-06-09)
DP offshore operations require that the vessel reference point is controlled in relation to a fixed reference frame. In some cases, the heading is allowed to change, searching for an adequate angle in which the environmental ...
The dynamic behavior of a parametrically excited time-periodic MEMS taking into account parametric errors
Micro-electromechanical systems (MEMS) are micro scale devices that are able to convert electrical energy into mechanical energy or vice versa. In this paper, the mathematical model of an electronic circuit of a resonant ...
Tools for improving feeding strategies in a SBR with several species
This paper analyzes feeding strategies in a sequential batch reactor (SBR) with the objective of reaching a given (low) substrate level as quickly as possible for a given volume of water. Inside the SBR, several species ...
The T2 chart with mixed samples to control bivariate autocorrelated processes
In this paper, we propose the use of the T2 chart with the mixed sampling strategy (MS) to monitor the mean vector of bivariate processes with observations that fit to a first-order vector autoregressive model. With the ...
Controle discreto com modos deslizantes em sistemas incertos com atraso no sinal de controle
(Universidade Estadual Paulista (UNESP), 2006-08-30)
Este trabalho apresenta três novas estratégias de controle discreto. O enfoque principal do trabalho foi dado ao Controle Discreto com Modos Deslizantes (CDMD) aplicados em sistemas que possuem atraso no processamento do ...

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 ...
Output control of continuous-time uncertain switched linear systems via switched static output feedback
This paper is devoted to the robust (Formula presented.) and guaranteed cost control problems for continuous-time switched linear systems with polytopic uncertainties, considering an output-dependent switching law and a ...
Pareto-based modulated model predictive control strategy for power converter applications
(Elsevier Ltd, 2019)
Modulated model predictive control (M 2 PC) allows fixed switching frequency operation of power converters, producing lower ripple and lower total harmonic distortion (THD) in the output signals than those obtained using ...
