A voltage regulation control strategy suitable for SRG with a ring winding structure

This paper proposes a scheme for applying space vector control method to a Switched Reluctance Generator (SRG) system with a ring winding structure. This paper focuses on the rectification system of SRG system, primarily analyzing the simulation model of the proposed system and the dual closed-loop control strategy for voltage and current. A solution has been developed to handle the strongly nonlinear and tightly coupled structure of the SRG when adopting the inner current loop control, and the issue of sector abrupt change that occurs when traditional control strategies are applied to the SRG system has been resolved. The performance of the SRG with a ring winding structure under different control strategies is compared in Simulink, verifying the effectiveness of the control strategy. Finally, the authenticity of the proposed control strategy is further validated on an experimental platform.
