锅炉蒸汽温度的广义智能控制系统设计与应用

Application and Design on Generalized Intelligent Control System of Boiler Steam Temperature

以具有时变特性、大惯性和非线性的锅炉蒸汽温度受控对象为背景,设计广义智能控制系统,给出闭环控制系统全局渐近稳定的充分条件及其数学证明。仿真实验和在火电厂锅炉蒸汽温度控制系统所取得的实际效果,验证了设计理念的实用性和有效性,较好地解决了控制系统稳定性和快速性的矛盾。

The contradiction of speediness and stability is a difficult problem in face of control theory study and control system design at all times.The paper takes time-variant,great-inertia and nonlinear controlled object as study background,designing generalized intelligent control system,and mathematical proof to sufficiency conditions of the closed-loop control system coming into asymptotically stabilization in full scope has presented.The practicability and the validity of the design method have been proven based on simulation tests and effect of engineering practice in boiler steam temperature control system of thermal power plant.It can better solve the contradiction of speediness and stability of control system.
