摘要 本文首先建立了三相四线电压型PWM整流器的PCHD数学模型。根据控制目标,基于PCHD模型,利用IDA-PBC设计了PWM整流器的无源控制器。由于IDA-PBC采取能量成形和注入阻尼,可使能量存储函数快速趋于期望平衡点,实现控制目的。由无源控制器确定出dq0坐标系下的开关函数是简单的代数表达式,可简化控制结构。由于无源控制器是在保证稳定的前提下,由注入阻尼的大小就可调节整流器的性能,具有易于调试和工程实现的特点。计算机仿真结果证实了基于PCHD模型三相四线电压型PWM整流器无源控制的可行性。

Abstract:PCHD(Port Controlled Hamiltonian with dissipativity, PCHD) model of three-phase four-wire voltage source PWM rectifier is set up first. According to control goal of PWM rectifier,based on PCHD model passivity based controller is designed by IDA-PBC(Interconnection and Damping Assignment Passivity-Based Control,IDA-PBC). Because of energy shaping and damping injecting used in IDA-PBC, storage function is made to go desired equilibrium point quickly and control objectives are realized . Switching function under dq0 coordinates educed by passivity based controller are simple algebraic expression and control structure can be simplified . Performances of PWM rectifier can be adjusted by damping injecting under ensuring stability. Therefore passivity based controller is easy debugging and realizable in engineering. Passivity based control based on PCHD model is proved feasible by Simulation results.
