摘　　要：以三相非隔离式交错并联VRM为研究对象,应用微分几何理论实现三相VRM的非线性解耦控制。首先在统一的开关脉冲函数下,建立三输入三输出仿射非线性模型;基于微分几何理论得到三相VRM的状态反馈线性化解耦控制规律;最后给出了仿真对比实验,结果表明基于状态反馈线性化控制的交错并联VRM有良好的动态品质和稳态特性。This paper obtains the nonlinear decoupled control laws of 3-phase non-isolated VRM by differential geometry theory.Firstly,the unified switch impulse function is given,and the three input and three output affine nonlinear model is built up.Secondly,the state variable feedback linearization control law of 3-phase VRM is given based on the differential geometry theory.At last,the simulation results show the performance on dynamic and steady state of VRM is good based on the state variable feedback linearization.
