Fault tolerant control of power electronic circuit based on MLD model
摘要
Abstract
Compared with traditional switching function model of power electronic circuit,mixed logic dynamic (MLD) model can accurately describe the changing process of circuit because the mixed logic dynamic model contains the control change and condition change of circuit. The MLD model of power electronic circuit is established in this paper. Considering that the MLD model contains the discrete variables,the traditional control method is no longer applicable. Therefore,the auxiliary logical variables and assisted continuous variable were introduced into the model predictive control (MPC). The fault tolerant control and realization steps of power electronic circuit based on MLD model and MPC were researched. The method has the ad-vantages of simple realization,good fault tolerance error performance,strong versatility. The feasibility and effectiveness of this method were verified by the example of fault-tolerant control of a three-phase four-leg inverter circuit.关键词
