| description | Abstract The study presents an intelligent, model-free current control strategy that eliminates the need for explicit plant models while efficiently reducing the effect of plant parameter perturbation. By employing a data-driven approach with fewer input features, the proposed scheme reduces the computational burden during training while maintaining high control performance. Unlike conventional model predictive current control (MPCC), which is computationally expensive because of solving optimization problems at each sample time, and requires precise plant models, the proposed method enhances system performance by addressing plant model discrepancies through data-driven techniques. Additionally, adaptive particle swarm optimization (APSO) is used to optimize the gain parameters of the outer speed control loop for improved dynamic performance. To verify the effectiveness of the data-driven control scheme, a comparative study with a conventional control scheme is presented. We verify that the switching states obtained from the model-based control design are learned with an accuracy of 94.8% using the proposed model-free data-driven approach. Test results show that the proposed approach outperforms traditional methods, offering superior steady-state performance, lower harmonic distortion, and increased robustness. |
