摘要

在大范围运行过程中，由于电厂的非线性动力学耦合，控制回路之间的相互作用会影响电厂的负荷跟随能力和频率调节效果。本文提出了一种模糊增益调度解耦控制方案，以改善电厂在整个运行空间的大功率漂移下的响应。该控制方案由串联的单回路PID控制器和逆交互补偿器组成。控制器和补偿器都采用模糊系统的增益调度，以覆盖整个操作空间。通过仿真实验对所提出的控制方案进行了验证。结果表明，大范围操作得到改善。

Fuzzy Gain-Scheduling PID+Decoupling Control for Power Plant Wide-Range Operation

Mostly during wide-range operation, load-following capability and efficacy for frequency regulation of fossil-fuel power plants may be affected by interaction among the control loops, caused by the non-linear coupled plant dynamics. This paper introduces a fuzzy gain-scheduling decoupling control scheme to improve plant response under large power excursions throughout the power plant operating space. The control scheme consists of single-loop PID controllers in series with an inverse interaction compensator. Both, the controllers and compensator are gain-scheduled with fuzzy systems to embrace the entire operating space. The proposed control scheme is evaluated through simulation experiments. Results show improved wide-range operation.
