摘要
Abstract
According to the topology of diode-clamped three-level rectifier,the decoupled state-space equations in synchronous rotating reference irame(d -q frame) were derived. The conventional two-closed-loop control method may fail to decouple when the system parameters and the model parameters are not completely matched. In order to realize realiable decoupling, the IMC method was brought into the inner-current loop control of PWM rectifier instead of conventional PI controller and this stategy was simulated using Matlab/Simulink. Simulation results demonstrate that the proposed IMC controller provides excellent performance both in steady-state and dynamic load variations. Besides,the design method is simple and easy to regulate.关键词
