This paper presents the stability analysis and control synthesis for a sampled-data control system which consists of a nonlinear plant and an output-feedback sampled-data polynomial controller connected in a closed loop. The output-feedback sampled-data polynomial controller, which can be implemented by a microcontroller or a digital computer, is proposed to stabilize the nonlinear plant. Based...

Inspired by a concrete industry problem we consider the input synthesis problem for hybrid systems: given a hybrid system that is subject to input from outside (also called disturbance or noise), find an input sequence that steers the system to the desired postcondition. In this paper we focus on sampled data systems—systems in which a digital controller interrupts a physical plant in a periodi...

A systematic evaluation procedure for the choice of sampling rate and anti-alias filter in sampled-data control is presented. It is based on a multi criteria H∞ optimization procedure, where sampled-data measures are introduced to capture the intersample behavior. The optimization scheme is based on linear matrix inequalities (LMIs) formulated in the delta operator, and the result is a low orde...

Continuous time models with sampled data possess several advantages over conventional time series and panel models (special issue 62:1, 2008, of Statistica Neerlandica). For example, data with unequal time intervals can be treated efficiently, since the dynamic model parameters of the system model are not affected by the measurement process. In the linear case, the nonlinear parameter restricti...
