Formal Design Methodology for Discrete Proportional-Resonant (PR) Controllers Based on Sisotool/Matlab Tool

This paper presents a formal methodology for the analysis and design for discrete-time proportional-resonant classic (PR) controllers applied to a single-phase DC/AC converter using Sisotool/Matlab. This tool allows observing the response of the system before being simulated or experimentally implemented. Also, it allows to integrate and visualize the classical control theory requirements (overshoot, settling time, etc.) with the design of Proportional Resonant (PR) controllers. Simulations results demonstrate the effectiveness of the methodology presented for the design of PR controllers.
