Online optimization of controller parameters based on power electronics semi-physical simulation platform

This paper designs a semi-physical simulation platform for power electronic control systems to make it easier to design and debug the control algorithm and parameters. The control algorithm is built up using MATLAB/Simulink, and the PC is connected to the actual power electronic circuit. This design realizes online comparison control algorithm and automatic debugging of the controller parameters. On this basis, the paper has also developed an online optimization function of the controller parameters to ensure a reasonable transient response. Experimental results demonstrate the practicality and effectiveness of the experimental platform. The control strategy is modified flexibly and it is suitable for teaching experiment and engineering debug.
