Abstract

: The outstanding performance of modern gas turbine power plants requires an efficient and robust control strategy in order to recover the losses caused by the undesirable effects and the instabilities related to their operation. Also, these losses can be the cause of their unstable dynamic behaviour during full-load and partial load operation in the unplanned shutdown state. Hence, choosing the right control strategy can improve the operation of this type of machine by increasing its efficiency by up to 60%. This paper proposes the implementation of an innovative control strategy based on a generalized predictive adaptive control algorithm for monitoring the rotation speed of a Solar Titan 130 gas turbine, with the purpose of considering the constraints related to the nonlinear behavior of a turbine during large variations in machine load. The aim is to automatically adjust the parameters of the regulator of the turbine’s control loop in real time, with a recursive estimation of these parameters. Using the experimental input/output measurements in order to study its behavior, by integrating the predictive control estimators, ensures the superior performance of the analyzed gas turbine in terms of energy, efficiency and robustness regarding the parametric uncertainties and the variation of the turbine load.

基于广义预测自适应控制算法的燃气轮机转速监测

：现代燃气轮机发电厂的卓越性能需要一种高效和稳健的控制策略，以弥补由不良影响和与其运行相关的不稳定性造成的损失。此外，这些损失可能是其在计划外停机状态下满负荷和部分负荷运行期间不稳定动态行为的原因。因此，选择正确的控制策略可以提高这种机器的运行效率，使其效率提高60%。本文提出了一种基于广义预测自适应控制算法的创新控制策略，用于监测Solar Titan 130燃气轮机的转速，目的是考虑在机器负载大变化期间与涡轮机非线性行为相关的约束。其目的是实时自动调整涡轮机控制回路调节器的参数，并对这些参数进行递归估计。通过集成预测控制估计器，使用实验输入/输出测量来研究其行为，确保了所分析的燃气轮机在能量、效率和鲁棒性方面的卓越性能，这些性能与参数不确定性和涡轮机负载的变化有关。
