摘要
针对舰用蒸汽动力装置的特点,根据热工动态原理,建立锅炉一汽轮机动态数学模型,应用多变量控制理论中的单向解耦法和多变量频域解耦设计法,将多变量控制系统化解为单变量控制系统,进行协调控制方案研究,给出协调控制系统设计的方法,并用参数优化方法获得了协调控制器参数。仿真运行结果表明,协调控制系统优于常规的PID控制系统。
A dynamic mathematical model for steam power plant boiler-turbine is set up using therrnodynarnic principle.The coordinated control schemes are investigated, and a method for designing the coordinated control system aregiven. The parameters of coordinated controller are synthetically optimized. Meanwhile, the multivariate controlsystern is turned to a single variable control system by using onesided decoupling and multivariate frequency domainapproach- The simulation results proved that the coordinated control system is far better than the conventionalPID controller.
