Performance evaluation of a DC-AC inverter controlled with ZAD-FPIC

Introduction− Power converters are used in mi-crogrids to transfer power to the load with a regulated voltage.

Description
Summary:Introduction− Power converters are used in mi-crogrids to transfer power to the load with a regulated voltage. However, the DC-AC converters present distor-tions in the waveform that can be improved with the help of real-time controllers.Objective−Evaluate the response in alternating cur-rent of the buck converter controlled with the ZAD-FPIC technique.Methodology−Based on the differential equations that describe the buck power converter, the ZAD and FPIC controllers are designed. Afterwards, simulations of the complete controlled system are made using Simulink of MATLAB. Then, the system is implemented experi-mentally and the controller is executed in real-time with the help of a DS1104 from dSPACE. In the end, several tests are carried out to check the effectiveness of the controller.Results− The results show that the controller allows good stability against different variations in the system and in the load.Conclusions−The ZAD-FPIC technique controls the variable and tracks changes in the waveform, magni-tude, and frequency of the reference signal. The control-ler presents good stability to different tests, tracking the reference signal after each event.
