摘　　要：在燃气轮机运行过程中,可转导叶易随压气机转速等状态量变化而频繁改变角度,继而引起振荡。这种可转导叶的振荡现象可能影响机组性能甚至导致喘振的发生。本文采用一种基于分散式多变量控制策略的新型自抗扰控制(ADRC)算法,对燃气轮机可转导叶设计了转速–导叶双变量自抗扰控制方法,并加入了死区和滤波功能,能够在保证机组转速稳定的同时抑制机组运行过程中可能出现的可转导叶抖动现象,可在不同工况下稳定机组状态,提高燃机效率。During the operation of gas turbine,the angle of inlet guide vanes is easy to change frequently with the change of compressor speed and other state variables,which will cause oscillation.This oscillation phenomenon of inlet guide vanes may affect the performance of the unit and even lead to surge.In this paper,we use a new active disturbance rejection control(ADRC)algorithm based on decentralized multivariable control strategy to design the speed-guide vane bivariate decentralized ADRC method for the gas turbine inlet guide vanes,and add the dead band and filtering functions,which can not only ensure stability of the unit speed,but also suppress possible inlet guide vanes jitter during the operation of the unit,stabilize the unit state under different working conditions,and improve efficiency of the gas turbine.
