摘　　要：针对穿孔机生产工艺特点及对电气传动系统的要求,设计了双闭环斩波串级调速控制系统。介绍斩波式串级调速系统的工作原理,说明其具有较硬的机械特性,适用于穿孔机的周期性短时工作负载。并设计电流内环和转速外环的双闭环自动控制系统,进一步提高穿孔工艺过程中电机转速的静态、动态品质,具有工程应用和推广价值。The double close-loop cascade speed control system by chopper is designed to suit the demand of electric driving motor system for piercing mill. By introducing the basic principle of the speed control system using cascade control method with IGBT chopper, which mechanical characteristic is hard and suitable for the periodicity changed short time working load of piercer. Further- more, double close-loop control system is designed for earning better static and dynamic performance in roll milling period. This method is worthy to be spread in engineering application.
