协调控制系统设计新思路

通过对火电单元机组控制对象的复杂特性(非线性、强耦合、大惯性)的分析，指出常规协调控制系统难于实现自动控制的原因，提出了将智能解耦控制、状态参量控制和Fuzzy-PID复合控制技术结合起来应用，构造协调控制系统设计的新方案，并在实践应用中取得了满意的控制效果，表明了这些设计思路的有效性。

A New Design Thread of the Coordination Control System

Through analzing the copmplicated characteristics of the thermal power unit's control objects, the paper indicates the reason of the difficult situation about the routine coordination control system to realize the automatic control, and proposes a new plan to construct the design of the coordination control system combining with the intelligent decoupling control, state parameter control, and the Fuzzy-PID technique, also the design has obtained the approving effect in the practice, and this reflects the validity of the design thread.
