摘　　要：提出了一种基于逆模型的火电机组负荷对象自适应解耦控制方法。根据系统的输入输出信息,建立机组负荷对象逆系统的模糊规则模型,并依据该逆系统模型实现对被控对象的近似线性化和基本解耦。论证了逆系统模型特征参数与控制系统中各控制器特征参数之间的内在联系,在此基础上形成了一种与机组负荷对象特性相匹配的自适应控制系统。文中通过仿真实例验证了该方法的有效性。An adaptive decoupling control method for thermal power unit based on inverse model was presented in this paper. According to the input and output information of the controlled object, a fuzzy rule inverse model of power unit was established, and the approximate linearization and basic decoupling for the power unit were realized using the inverse model. The inner relationships between the characteristic parameters of the inverse model and each controller in the control system were demonstrated, and on the basis of these, an adaptive control system which matches with the properties of the power unit was formed. The effectiveness of the proposed method was verified by the simulation in this paper.
