The rapid development of three-phase grid-forming micro-source inverter based on SMC and PI control

Abstract

Abstract-The rapid development process of a proposed three-phase grid-forming micro-source inverter is presented in the paper. Sliding mode control (SMC) and PI control strategies are adopted synthetically to implement the dual closed-loop controller. In order to avoid the repeated selection of control parameters, the particle swarm optimization (PSO) algorithm is applied for parameters' optimization. Simulation results certificate the correctness of the proposed controller. And then, the automatic generation of control codes is realized based on the model design method. The actual hardware experiments corresponding to the simulation ones are presented in the paper. The results demonstrate that the inverter based on the rapid development is effective and the proposed controller performs better robustness property over conventional PI-based control strategy.

“…A double feedback controller realized by the SMC and proportional-integral control has been applied to the microsource inverter, where a PSO algorithm is employed for the optimization of the control parameters. The sliding-mode reaching law does not precisely strike the requisite sliding manifold, so the resulting waveforms still suffer from considerable distortion [51]. A brushless DC motor actuated water pumping system dependent on the PV supply has been proposed.…”
