摘　　要：该文基于微分几何理论,在建立三相电压型PWM整流器仿射非线性模型基础上,提出其状态反馈精确线性化非线性控制策略,实现了三相电压型PWM整流器无功功率和有功功率的解耦控制。研究表明,状态反馈精确线性化非线性控制能较理想地实现三相电压型PWM整流器控制解耦,完成其功率因数校正及整流器输出特性控制的功能。文中给出了完整的理论分析及实验研究结果。Based on the feedback linearization theory of differential geometry theory, an affine nonlinear mode of three phase voltage source PWM rectifier in the rotating frame d-q is set up by applying impulse mode integral method. The feedback linear model of three phase voltage source PWM rectifier is obtained and decoupled reactive and active power control strategies of three phase voltage source PFC rectifiers are proposed. Research shows that this proposed control scheme can realize decoupled control of three phase PWM PFC rectifiers with perfect dynamic characteristics. The theory is verified by the simulation and experiment.
