Comparative study of LMI-based output feedback spr synthesis for plants with different numbers of inputs and outputs
New Linear Matrix Inequalities (LMI) conditions are proposed for the following problem, called Strictly Positive Real (SPR) synthesis: given a linear time-invariant plant, find a constant output feedback matrix Ko and a ...
LMI-based digital redesign of linear time-invariant systems with state-derivative feedback
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 ...
Variable structure control of switched systems based on Lyapunov-Metzler-SPR systems
This paper presents two Variable Structure Controllers (VSC) for continuous-time switched plants. It is assumed that the state vector is available for feedback. The proposed control system provides a switching rule and ...
Síntese de sistemas estritamente reais positivos através do critério de routh-hurwitz
Given a linear time-invariant plant Gol(s) with one input and q outputs, where q > 1, a method based on the Routh-Hurwitz Stability Criterion is proposed to obtain a constant tandem matrix F ∈ ℝq, such that FGOl(s) is a ...
Mixed order robust adaptive control for general linear time invariant systems
We provide a solution to the adaptive control problem of an unknown linear system of a given derivation order, using a reference model or desired poles defined in a possibly different derivation order and employing continuous ...
Robust state-derivative feedback LMI-based designs for multivariable linear systems
(Taylor & Francis Ltd, 2007-08-01)
In some practical problems, for instance in the control systems for the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. New necessary and sufficient ...
