摘要
Abstract
As one of the important components in the power plant control system,the digital electro-hydraulic control system(DEH)of the steam turbine plays a vital role in the stable and efficient operation of the power plant.Due to the complex structure of DEH control system and the changeable internal conditions,it is easily affected by load disturbance and air pressure disturbance,while the traditional fuzzy PID control method has low adjustment accuracy,weak anti-interference ability,and unsatisfactory con-trol effect.In order to better solve this problem,this paper proposes a control scheme based on disturbance observer(DOB),which combines with fuzzy PID control and adopts feedforward control to improve the dynamic performance of traditional fuzzy PID control.Compared with the traditional fuzzy PID control method,the simulation experiments are compared and analyzed under different working conditions and influencing factors.The results show that the proposed control scheme has faster adjustment speed and stron-ger anti-interference performance than the traditional fuzzy PID control method and robust performance.关键词
