摘要
针对火电机组被控对象非线性、迟滞、燃料大惯性并存的特性,建立了330 MW单元机组协调控制系统非线性模型,并对此模型在额定工况点下进行线性化,以此线性化模型为基础,在机组原有的协调控制系统中增加多变量解耦控制器,进而设计出与之对应的多变量协调控制系统,并通过工程试验与机组原有的协调控制效果相比较,实际结果证明了多变量智能协调控制系统的有效性和实用性。
The controlled object for the thermal power is a rather complicated multivariable nonlinear control system,which is characteristic of nonlinear,delay and great inertial. A nonlinear model of the coordinated control system for 330 MW unit plant was constructed, and it was linearized under rated work conditions. The multivariable coordinated control system of increase in multi-variable decouping controller for original coordina- ted control system is designed to the corresponding systems, and control result contrast of field investigation shows its validity and practicability.
