摘　　要：针对火电机组汽温控制中的对象特性多变、抗扰动性能差、控制器难于整定等问题,将智能优化算法应用于汽温控制系统中,系统地提出了一套适用于工程实际的汽温控制优化策略,即高精度对象辨识、控制预估算法、扰动预估算法、控制器的鲁棒优化等,通过一个具体实例说明应用步骤,现场应用证明了该方法的有效性。To solve the questions in steam temperature control system such as the object variability, poor performance of anti-disturbance and controller tuning difficult issues, this paper proposes a set of optimization methods. In this paper, intelligent optimization algorithm and a set of method are applied to actual steam temperature control system, namely, high-precision target identification, control forecast algorithm, perturbation forecast algorithm and the controller robust optimization. The application of the method steps is explained by a ensample, and the effectiveness of the method is proved by locale application.
