摘　　要：通过对泵节能调速控制系统的原理分析,建立数学模型,利用奈魁斯特稳定判据分析其稳定性,判断系统的能观性和能控性,利用极点配置改善系统的性能,通过simulink进行仿真,比较系统的性能.利用PLC编程、Wincc flexible与触摸屏结合对系统进行组态,实现友好的人机界面控制.结果表明:泵节能调速控制系统稳定性良好,具有能观性和能控性,极点配置提高了系统的性能.通过实验验证了泵节能调速控制系统能够得到精确的控制,从而实现泵节能调速控制,满足工业生产要求,降低能源的消耗.By analyzing principle of the energy-saving pump speed regulation control system, the mathematical model is established. The stability of the system is analyzed by Nyquist stability criterion, and the observability and controllability is judged. The pole assignment is used to improve the performance of the system. The performance is compared by Simulink simulation. By using PLC programming, Wince flexible combined with touch screen on system configuration, the friendly HMI control is realizes. Results show the followings： The stability of the energy-saving pump speed regulation control system is good, it has good observability and controllability, and the performance of the system is improved by pole assignment. The energy-saving pump speed regulation control system can be precisely controlled is verified by experiment, thus energy-saving speed regulation control of the pump is realized to meet the requirements of industrial production and reduce energy consumption.
