三参数自适应虚拟直流电机控制研究
Research on Three-Parameter Adaptive Virtual DC Motor Control
摘要
Abstract
Adding the virtual DC motor control into DC converter can provide additional inertial and damping support for the DC system.But the constant control parameters in the traditional virtual DC motor control make it lack of flexibility.On the basis of traditional virtual DC motor control,the two-parameter adaptive virtual DC motor control can improve the stability of DC bus voltage by realizing the flexible change of inertia and damping parameters,but the improvement effect is limited.The control parameters other than inertia and damping also have great influence on the stability of DC bus voltage.To solve this problem,this paper takes the dual active full-bridge DC converter as topology,analyzes the influence mechanism of inertia,damping and armature resistance on the voltage stability of DC bus,and proposes the three-parameter adaptive virtual DC motor control.Finally,through simulation and experiment,the advantages of three-parameter adaptive virtual DC motor control in suppressing DC bus voltage fluctuation and improving system dynamic response speed are verified.关键词
