汽包锅炉的动态模型结构与负荷/压力增量预测模型

探讨了一以分考虑系统非线性特性的汽包锅炉动态模,描述了动态模型的结构,并探讨了求取动态模型未定参数的方法,为构造了新的协调控制系统,文中给出了负荷／压力增量预测模型。利用这组方程,给出了基于这个预测模型的解耦策略,仿真实例验证了动态模型的有效性以及新协调控制系统的控制品质。

DRUM BOILER DYNAMIC MODEL AND LOAD/PRESSURE INCREMENT PREDICT MODEL

This paper introduces one kind of drum type boiler dynamic model structure, which considering the system nonlinearity. The dynamic model structure is introduced, and we bring forward the equations, which can solve the uncertain parameters. In order to construct the new Coordinated Control System (CCS) system, the dynamic equations predicting load/pressure increment are introduced. A new discoupling method then is introduced based on those equations. The simulations have illustrated the efficiency of the dynamic model and the performance of the new CCS system.
