非线性控制在高速透平膨胀机安全生产中的应用

Nonlinear Control Used in the Safe Production of High Speed Turboexpander

在传统PID调节的基础上,采用低速逐次逼近工作方式,利用计算机调节步进电机的转速,实现高速透平膨胀机安全运行时气体轴承进气量的控制,避免人为操作事故。

<Abstrcat> This paper based on traditional PID adjustor and the method of approach gradually by using computer to regulate the rotate speed of the step motors, discusses the realization of control of the capacity of air flow from air bearing when high speed turboexpander is running safely, which is capable of avoiding the operation accident.
