摘　　要：为了提高电流型PWM整流器网侧功率因数和系统抗干扰能力,提出了采用互联和阻尼分配无源控制方案设计系统控制器的新型控制策略。根据能量成型和端口受控哈密顿控制原理,建立了电流型PWM整流器的端口受控耗散哈密顿(PCHD)模型,根据系统控制器的设计目标,求取了期望稳定平衡点。通过配置与系统结构兼容的能量函数,在期望稳定平衡点处设计了镇定的控制器,实现了电流型PWM整流器单位功率因数运行、直流电流快速达到期望值并稳定运行于平衡点的控制目标,仿真结果证明了该方案的可行性。In order to improve the power factor and anti-interference ability of current mode PWM rectifier,presents a new control strategy which is based on interconnection and damping assignment passivity-based control scheme. Current mode PWM rectifier port controlled dissipative Hamihonian （PCHD） model is established according to the principle of energy-shaping and port controlled Hamiltonian control, the expected stable equilibrium points are calculated according to the system controller design goals. Through the energy function configuration which is compatible with system structure, the stabilization controller is designed on the expected stable equilibrium points, it realizes unit power factor operation of the current-mode PWM rectifier and the dc current reaches expectations fastly and steady runs on the stable equilibrium points, the simulation results prove the feasibility of the scheme.
