- Guaranteeing asymptotic zero intersampling tracking error via a discretized regulator and exponential holder for nonlinear systems Bernardino Castillo Toledo Guillermo Obregón Pulido Ingeniería Nonlinear Systems Regulation Theory Discrete time control In this paper we present the design of a robust discretized controller based in the theory of regulation for nonlinear systems. In the general command tracking and disturbance rejection problem, it is known that a sample data controller using zero order holder may only guarantee asymptotic tracking at the sampling instances. We show that by means of a so-called exponential holder, we are able to guarantee asymptotic zero output tracking error, not only in the sampling instant, but also between these instant. Some considerations on the design of exponential holders are presented. The application in simulation to some typical nonlinear systems shows the good performance of the proposed scheme. 2003 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47410303 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.3 Vol.1
