Experimental Validation of a Hybrid PI–SO-SMC Approach for Zero-Sequence Circulating Current Suppression in Parallel Inverters
This paper presents an experimental investigation of a dual-inverter induction motor (IM) drive system for zero-sequence circulating current (ZSCC) suppression using a novel hybrid PI–SO-SMC strategy. The proposed method combines a proportional–integral (PI) regulator and a second-order sliding mode controller (SO-SMC)...
