- Numerical and Experimental Comparison of the Control Techniques Quasi-Sliding, Sliding and PID, in a DC-DC Buck Converter Nicolás Toro García Yeison Alberto Garcés Gómez Fredy Edimer Hoyos Velasco Ingeniería DC ZAD FPIC DPWM delay time In this paper the Sliding Mode Control (SMC), PID and ZAD (Zero Average Dynamic) strategies are applied to an electronic DC-DC power converter. Time behavior for each controller is shown for numerical solution and experimental realization. The results in SMC and PID are contrasted with a ZAD-FPIC controller combined with a recently developed strategy named FPIC (Fixed Point Induction Control). Stability in SMC is guaranteed by the Lyapunov theorem. The PID controller is designed in an analytical way using pole placement. The main problem with the physical realization was the sample and hold in the variable acquisition system, in addition to time delay introduced by the computing process. From a practical point of view, the ZAD-FPIC technique has advantages no shown by PID and SMC working with sample and hold, these advantages have been corroborated experimentally. The designs have been tested in an RCP (Rapid Control Prototyping) system based on DSP from the dSPACE platform. Both numerical performance and experimental performance agree. 2018 artículo científico 0122-1701 https://www.redalyc.org/articulo.oa?id=84956661005 https://www.redalyc.org/journal/849/84956661005/ https://www.redalyc.org/journal/849/84956661005/html/ https://www.redalyc.org/journal/849/84956661005/84956661005.epub https://www.redalyc.org/journal/849/84956661005/movil en http://www.redalyc.org/revista.oa?id=849 Scientia Et Technica application/pdf Universidad Tecnológica de Pereira Scientia Et Technica (Colombia) Num.1 Vol.23
