摘　　要：为了获得传感器迟滞所引起的燃气轮机监测信号迟滞现象对燃气轮机转速控制的影响规律,首先建立监测信号迟滞模型,并将其与燃气轮机模型和控制系统进行耦合,进行转速迟滞、压力迟滞和温度迟滞对燃气轮机转速控制的影响研究。最后,进行PID控制参数与监测信号迟滞耦合对燃气轮机转速控制的影响研究。本文研究主要从燃料量、燃料量调节输出、燃气发生器转速、调节时间的角度进行分析。结果表明,转速迟滞和压力迟滞是燃气轮机转速控制的主要影响因素;温度迟滞对燃气轮机转速控制无影响;改变PID控制参数有利于提升监测信号迟滞时的燃气轮机转速控制性能。In order to obtain the influence law of gas turbine monitoring signal hysteresis caused by sensor hysteresis on gas turbine speed control,firstly,the monitoring signal hysteresis model is established and coupled with the gas turbine model and control system.Secondly,the influence of speed hysteresis,pressure hysteresis and temperature hysteresis on gas turbine speed control is studied.Finally,the influence of PID control parameters and monitoring signal hysteresis coupling on gas turbine speed control is studied.This paper mainly analyzes the fuel quantity,fuel quantity regulation output,gas generator speed and regulation time.The results show that speed hysteresis and pressure hysteresis are the main influencing factors of gas turbine speed control,temperature hysteresis has no effect on the speed control of gas turbine,changing PID control parameters is conducive to improving the speed control performance of gas turbine when the monitoring signal is delayed.
