In this paper, an H(∞) robust controller has been designed for an identified model of MONTAZER GHAEM power plant gas turbine (GE9001E). In design phase, a linear model (ARX model) which is obtained using real data has been applied. Since the turbine has been used in a combined cycle power plant, its speed and also the exhaust gas temperature should be adjusted simultaneously by controlling fuel signals and compressor inlet guide vane (IGV) position. Considering the limitations on the system inputs, the aim of the control is to maintain the turbine speed and the exhaust gas temperature within desired interval under uncertainties and load demand disturbances. Simulation results of applying the proposed robust controller on the nonlinear model of the system (NARX model), fairly fulfilled the predefined aims. Simulations also show the improvement in the performance compared to MPC and PID controllers for the same conditions.
本文为经辨识的 MONTAZER GHAEM 燃气轮机（GE9001E）模型设计了 H(∞)鲁棒控制器。在设计阶段，应用了使用实际数据获得的线性模型（ARX 模型）。由于涡轮机已用于联合循环发电厂，因此通过控制燃料信号和压缩机进气导叶（IGV）位置，应同时调整其速度和废气温度。考虑到系统输入的限制，控制的目的是在不确定和负载需求干扰下将涡轮机速度和废气温度保持在期望范围内。在所提出的鲁棒控制器在系统的非线性模型（NARX 模型）上的应用的仿真结果中，相当好地满足了预定目标。仿真结果还表明，与 MPC 和 PID 控制器相比，在相同条件下，性能得到了改善。
