12/14磁悬浮开关磁阻电机悬浮系统解耦控制策略
Decoupling Control of Suspension System for 12/14 Bearingless Switched Reluctance Motor
摘要
Abstract
The suspension force displacement stiffness coefficient and current stiffness coefficient of the 12/14 bearingless switched reluctance motor are dynamically coupled by the rotor position,and have nonlinear time-varying characteristics,which seriously affect the operational robustness of the suspension system.Aiming at the above problem,this paper proposes a suspension control system with a coupled suspension force regulator(CSFR).Firstly,the nonlinear time-varying law and mathematical model of suspension force are revealed and established.The nonlinear time-varying model is further decomposed into position decoupling suspension force model and nonlinear time-varying coupling components.Among them,the position decoupling suspension force model(PDSFM)is used as the direct feedback model of the suspension system,and the coupled suspension force observer(CFO)is designed based on the PDSFM,which can observe the nonlinear time-varying coupled component and feed it forward to the suspension control system as an external disturbance.Finally,simulation analysis and experimental verification of the effectiveness of the coupled suspension force regulator and the control system are carried out.The results show that the proposed control method can effectively solve the dynamic coupling of the rotor position to the suspension system and improve the operational robustness.关键词
