Dual-Loop Compensation Voltage Control for Linear Switched Reluctance Generators

In the wave power generation system, the single-loop voltage control method of asymmetric bilateral linear switched reluctance generator (ABLSRG) often encounters the problems of low accuracy and poor robustness of output voltage. To solve such problem, a dual-loop voltage control method is often used. However, the increase of the power generation capacity will lead to insufficient output voltage accuracy for the dual-loop control method. In order to increase the capacity of the power generation system to ensure the accuracy of output voltage, this paper proposes a dual-loop compensation voltage control method of double ABLSRGs. Experimental results show that this compensation method can effectively reduce the steady-state error while increasing the power generation capacity, and shows good robustness under the condition of wave velocity change.
