摘　　要：针对某和谐型机车中Buck斩波电路,采用典型I型和II型系统设计方式,给出了电压外环和电流内环双环调节器设计的依据和参数选择的方法,通过零极点重新配置提高电流内环的带宽和电压外环的稳定裕度。相比于单电压环,双环控制器可以更加灵活地配置系统参数,从而提高系统的稳定性和动态性能。仿真和试验结果显示,负载无论突投还是突切,双闭环控制动态响应明显优于单闭环,证实了参数计算的有效性。This paper provided the double-loop regulator design and parameter calculation for Buck chopper on a certain HXDx locomotive by using typical I type and II type system design, which improved the bandwidth of inner current loop and stability of outer voltage loop through reallocation of zero and pole. Compared to single-loop control, the double-loop control could configure the system parameter more flexible, which could improve the stability and dynamic performance. The simulation and experiment showed obviously that double-loop control was superior to single-loop control especially in loading and unloading, which validated the feasibility of the calculation.
