摘　　要：针对火电厂锅炉过热系统的时变和非线性的特点,提出了模糊多模型的控制方法。对若干典型工况点建立固定模型,并设计相应的局域控制器,进而用T-S模糊模型合成出协调控制系统的全局控制器,解决了多模型切换过程中存在的扰动问题。仿真结果验证了该方法的有效性。A fuzzy multi-model control method is proposed for the characteristics of the super-heated system with time varying and nonlinearity in the power plant. Local controllers are designed for the models which are built at typical operation points, and a global controller of the coordinated control system is composed by T-S fuzzy model. The problem of disturbance in existance of multi-model switching course is resolved through this method. The computer simulation results show the effectiveness of this method.
