Diseño y simulación de un control dual por modos deslizantes para control de un tanque de neutralización de PH.

Abstract

This document presents the design and simulation of sliding mode controller based on the definition of dual mode control (DUAL-SMC), applied to a highly non-linear process. The present document will consist of two volumes in terms of theoretical development. The first volume starts with the theoretical foundations of SMC control, as well as Dual control. In addition, characteristics are detailed on the complex dynamics that the test process presents pH neutralization tank. Then, in the methodological framework, the analysis, validation, and modeling of the process is carried out by applying the empirical method, so that the characterization of the process parameters is as close as possible to the real process for an adequate tuning of the controller. The SMC controller with PID surface is designed, which will serve to compare the performance of the proposed controller. Finally, the DUAL-SMC type PID/PD control is turned, and the results obtained in contrast to the classic SMC are shown.
