Diseño y simulación de un esquema de control dinámico en modo deslizante para sistemas con respuesta inversa.

Abstract

Within the industrial processes with difficult dynamics to control we find the ones that have an inverse response, for which we have developed classical controllers type PID and structures with internal model within which a compensator proposed by Linoya is highlighted, which significantly reduces the effects of the inverse response in closed loop control. In the sliding mode control (SMC), process approximations are made to first order systems with delay, thus obtaining the controller in a simple way, taking advantage of its robustness in presence of disturbances, noise and modeling errors. In this project it shows a new type of sliding mode controller, using a second order transfer function with a zero and the Linoya compensator, called dynamic sliding mode control (DSMC). The DSMC will be applied to a linear plant and a nonlinear plant, both with inverse response. The new control law that is generated reduce the problem that has control by sliding mode are the high frequency oscillations also known as chattering through an integral action and in turn decreases the inverse response.
