Performance Analysis of Three-Phase Grid-Connected Inverter with Model Predictive Control Method in PIL Test Environment

Processor-in-the-loop (PIL) is a testing technique that allows designers to evaluate a microprocessor that will enable them to control a system running in an imaginary environment to emulate the system behavior. The system is realized via the PC in the fictional environment, while the control algorithm is implemented via the real-time microprocessor. In power electronics applications, PIL testing is applied to analyze the accuracy of the code to be run on the microprocessor. In this paper, using the classical Model Predictive Control (MPC) method, the PIL experiment of a three-phase grid-connected inverter system was realized in the Matlab/SIMULINK environment. According to the results of the PIL experiment, the system's stable performance confirmed the theoretical concept by using the MPC method.
