滑模变结构控制H6结构逆变器的非线性行为和稳定域
Non-linear Behavior and Stability Domain in Sliding Mode Controlled Inverter with H6-type
摘要
Abstract
In order to analyze the non-linear behavior and stability domain of the sliding mode controlled inverter with H6-type (SMCI-H6) system,the discrete time iterative model of the SMCI-H6 system is established with stroboscopic map method.The non-linear behavior and stability of SMCI-H6 is investigated by analyzing folded diagram,time-domain simulation,spectrum,and fast-scale stability criterion.To solve the problem of narrow stable domain of SMC coefficient ke,an improved control is proposed.The results indicate that a state mutationphenomenon,that is the period-1 state mutation to the period-2 state,is discovered.Meanwhile,the stability domain of ke is [0,0.021].Results of simulation and experiments show that the stability domain ofke is about 2.29 times wider in the inverter with H6-type,which is controlled by the improved control.The research results can be used to analyze the non-linear behavior and stability domain of the SMCI-H6 system.关键词
