复合控制H5逆变器的非线性动力学分析
Nonlinear dynamics analysis of H5 inverter under composite control
摘要
Abstract
In order to enhance the stable operating region of the system,a composite control strategy integrating PI control with power-rate reaching law sliding mode control is introduced into H5 inverter,and the bifurcation and chaos phenomena of the system are analyzed.The state equations under each mode are obtained based on the operating principle of the inverter,and the discretization processing of the state equations is conducted by means of the stroboscopic mapping method,so as to construct the mathematical model of the system.The nonlinear behaviors exhibited by control parameters and main circuit parameters under both composite control and PI control are analyzed by integrating bifurcation diagrams,fold diagrams,and Matlab/Simulink simulations,and their stable operating regions are determined.The fast-slow stability theorem is used to analyze the system stability.In order to further validate the correctness of theoretical analysis and numerical simulations,the experimental verification is carried out based on dSPACE platform.The results demonstrate that,in comparison with PI control,the composite control can significantly expand the stability regions for both control parameters and main circuit parameters,effectively suppressing chaos behavior of the inverter.These findings provide a theoretical basis for the design and tuning of H5 inverters.关键词
