摘　　要：以LCL滤波器的三相电压源脉冲宽度调制整流器为载体,通过建立具有耗散的端口受控哈密顿模型,构建基于互联和阻尼分配无源控制算法的无源控制策略,利用粒子群算法对控制参数进行离线优化,并对控制系统进行仿真试验。结果表明,优化后的控制系统抗扰动能力及暂态性能均有明显提高,具有较好的稳定性和鲁棒性,利用无源控制策略能有效降低其网侧电流的谐波含量和抑制谐振现象,使脉冲宽度调制整流器的整体性能得到有效提升。Using the three-phase voltage source pulse width modulation rectifier of LCL filter as the carrier,and by establishing a dissipative port controlled hamiltonian model,the passivity-based control strategy based on the passive control algorithm of interconnection and damping distribution was obtained.The control parameters were optimized off-line by particle swarm optimization algorithm,and simulation experiments on the control system were conducted.The results show that the anti-disturbance ability and transient performance of the optimized control system are significantly improved,with better stability and robustness.The harmonic content of the grid side current is reduced and the resonance phenomenon is suppressed by applying passivity-based control strategy;therefore the overall performance of the pulse width modulation rectifier is effectively improved.
