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 ...
LMI-based digital redesign of linear time-invariant systems with state-derivative feedback
(2009-12-01)
A simple method for designing a digital state-derivative feedback gain and a feedforward gain such that the control law is equivalent to a known and adequate state feedback and feedforward control law of a digital redesigned ...
Identification of structural parameters for active vibration control
(2006-12-01)
The study of algorithms for active vibration control in flexible structures became an area of enormous interest for some researchers due to the innumerable requirements for better performance in mechanical systems, as for ...
H ∞ state feedback control of discrete-time Markov jump linear systems through linear matrix inequalities
(2011-12-01)
This paper addresses the H ∞ state-feedback control design problem of discretetime Markov jump linear systems. First, under the assumption that the Markov parameter is measured, the main contribution is on the LMI ...
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 ...
