Comparative Study of Discrete PI and PR Controller Implemented in SRG for Wind Energy Application: Theory and Experimentation

The Switched Reluctance Generator (SRG) has been widely studied for Wind Energy Conversion Systems (WECS). However, a major drawback of the SRG system adopting conventional control is slow response DC link voltage controller. In this paper, Proportional Resonant (PR) strategy proposed to output improve fast response. model high non-linearity, which makes design controllers difficult task. For reason, important practical engineering aspect work role played by linearization in testing sensitivity PR controller performance specific parameter changes. characteristics steady-state behaviors SRG-based WECS under different approaches are simulated and compared. implemented on digital signal processor (TMS320F28379D). experimental results carried out using 250 W 8/6 prototype assess compared with traditional Integral (PI) strategy. show that enhances SR power generation WECS. Compared PI control, rise settling times reduced 45% 43%, respectively, without an overshoot.
