of the fast tracking performance and detection precision of OVS, the relationship between the closed-loop gains and the optimal ranges of the values of control parameters are derived. Based on the theoretical analysis, we have designed a hardware circuit to extract the closed-loop error with high precision, and wrote a control algorithm to optimize the dynamic performance. The experiment results demonstrate the effectiveness of our proposed method, and the dynamic performance of theOVSsystemhasbeengreatlyimprovedwhilethehighdetectionprecisioniskept.Theresultofourresearchisofsignificance to the application of OVSs in electric power systems
