非线性MIMO系统线性化在火力发电设备锅炉系统中的应用

APPLYING LINEARIZATION OF NONLINEAR MIMO SYSTEM TO BOILER CONTROL SYSTEM IN THERMAL POWER PLANT

对于含有输入滞后特性的多输入多输出（MIMO）非线件系统．本文提出了一个对输入输出进行线性化的方法，并引入Smith预估器对输入滞后进行补偿。线性控制器的设计和时间滞后补偿器的设计是相互独立的。本设计方法通过对火力发电设备锅炉控制系统的仿真试验中得到验证。

This paper proposes the application of a Smithlike predictor in the control system consisting of an input-output linearization of MIMO nonlinear systems with input time delays. Design of the linearized controller and that of the dead-time compensator are separate from each other. The effectiveness of the presented method is tested in boiler control system simulation of a thermal power plant.
