摘　　要：针对水轮机调速系统具有非最小相位特性的问题,本文以A电站调速系统控制改进为背景,将线性自抗扰控制(LADRC)策略应用于水轮机调速系统中,文章分析了线性自抗扰控制的策略,构建了线性自抗扰控制的仿真模型,对水轮机调速系统的线性自抗扰控制与传统PID控制进行仿真对比。仿真结果表明:线性自抗扰控制能够很好的减少负调并缩短调节时间,同时对工况变化和扰动具有良好的控制效果。In view of the non-minimum phase feature of the turbine governor system,this paper applies the Linear Active Disturbance Rejection Control(LADRC)strategy to the turbine governor system.This paper presents the principle of the turbine governor system,analyzes the LADRC strategy,builds the simulation model of LADRC,and conducts a simulation comparison between the LADRC and the traditional PID control of the turbine governor system.The simulation results indicate that LADRC can significantly reduce the negative regulation and shorten the adjustment time,and simultaneously has excellent control effects on working condition changes and disturbances.
