Abstract：The conventional proportional plus integral (PI) regulators control the current components #em/em#m and #em/em#t at synchronous coordinate. When the controlled system has multiple inputs and outputs, especially there has intense cross-coupling between the variables, this kind of regulator could not meet the system requirements. Being added a forward feedback decoupling may improve the performance. A novel current regulator with complex state variables for electrically excited synchronous motors is proposed based on the zero-pole diagram. Simulation results show that this kind of current controller with complex state variables can realize decoupling between #em/em#m and #em/em#t as well as the perfect dynamic and steady response.
