Output Feedback Sampled-Data Control of Nonlinear Systems in Output Feedback Form
This paper deals with sampled-data control of nonlinear systems in the output feedback form. A sampled-data control strategy is proposed based on the existing control design in the continuous-time domain via output feedback. The proposed control uses the sampled output and a discrete-time implementation of filters involved. The overall stability of the system under the proposed control has been...
متن کاملOptimal Sampled–Data State Feedback Control of Linear Systems ⋆
This paper addresses and solves two optimal state-feedback control design problems for sampled-data systems. First, we reformulate the closed-loop system as a special linear hybrid system. Then, two theorems are developed to evaluate the H2 and the H∞ performances of hybrid systems using specific two-point boundary value problems. Both theorems are adapted to provide optimal control conditions,...
متن کاملSingular Perturbation Theory in Output Feedback Control of Pure-Feedback Systems
This paper studies output feedback control of pure-feedback systems with immeasurable states and completely non-affine property. Since availability of all the states is usually impossible in the actual process, we assume that just the system output is measurable and the system states are not available. First, to estimate the immeasurable states a state observer is designed. Relatively fewer res...
متن کاملConvex initialization of the H2-optimal static output feedback problem
Recently we have established a link between invariants for quadratic optimization problems and linearquadratic (LQ) optimal control [1]. The link is that for LQ control one invariant is ck = uk − Kxk, which yields zero loss from optimality when controlled to a constant setpoint c = cs = 0. In general there exists infinitely many such invariants to a quadratic programming (QP) problem. In [2] we...
متن کاملMixed discrete/continuous specifications in sampled-data H2-optimal control
The increasing use of digital equipment in control in the last half century made a tremendous impact on controller design methodology. On the other hand, it had little affect on the control problem formulation: the control goals to a large extent still remain those of the analog world. The goal of this paper is to introduce and justify a new approach to sampled-data control system design, which...
