摘要(Abstract)：

在实际工业生产过程中，时延会对控制系统的性能产生不利影响，甚至导致控制系统不稳定。从切换系统角度研究了重型燃气轮机转速/功率控制回路的时延稳定性问题，以某电厂GEMS109FA275MW重型燃气轮机在100%负荷下的模型为研究对象，通过增广状态变量，选择时延变化作为切换信号，将含有时变时延的转速/功率控制回路转换为一类切换系统。运用范数相关引理，推导出确保含有时变时延的转速/功率控制回路稳定的充分且必要条件，并给出稳定性验证算法，同时基于国产重型燃气轮机Nu CON控制系统进行了硬件在环仿真实验，验证了所提理论结果的正确性。该研究结果可为国产重型燃气轮机控制系统设计和参数调整提供理论参考。
