Abstract

It is proposed, in this paper a dynamic matrix control (DMC) with an anti-windup (AW) based on linear matrix inequalities (LMI). The DMC-AW control is applied in the ballbeam system, in which the main purpose is to control the ball position on a rotating beam. System modeling was performed, which presented two degrees of freedom. For the mechanical system implementation a microcontroller, an ultrasonic sensor, and a servo motor were used. The proposed control was implemented both numerically with the software MATLAB and with the microcontroller ATmega328Pu. The simulation results validated the eciency of the proposed DMC-AW and showed that the approach improves the response of the system under input saturation.
