Diseño e implementación de controladores clásicos y robustos en una tarjeta embebida, aplicados a un modelo simulado de un convertidor dc/dc de topología buck-boost de fase no mínima

Abstract

This work presents the design simulation and implementation of classic controllers such as the PI controller and robust controllers such as the SMC, SMC-IMC, DSMC controllers , for voltage control in the load of a non-minimum Phase Buck-Boost converter, this system it is simulated in the Simulink / Matlab software, so this activity is similar to a Hardware in the Loop (HIL) simulation. The design of the robust controllers is based on an approximate reduced order model of the system to be controlled, and in the case of the SMC-IMC and DSMC controllers, an internal model scheme is used to counteract inverse response dynamics. For the analysis of the performance of the controllers in the system, indices such as the ISE and TVU are used, while with the help of radial graphs the results delivered by the indices are graphically explained. Finally, a graphical interface is made to visualize the results obtained.
