| 摘 要： | 本文概述了对象数学模型衰减振荡闭环工程辨识方法的理论基础,并在压力气动仪表控制系统实验装置上作了试验,求得了实验压力对象的简化数学模型.根据所得模型,应用仿真程序,在微型机上进行了数字仿真.仿真结果表明:参数误差较小,可适用于实际系统的在线辨识,为构成一类简单的自适应PID控制系统创造了条件.对一些具有非线性特性的实际对象,采用衰减振荡闭环试验方法,限制被调参数的变化范围,得到的对象模型比较接近正常工况,具有工程应用的价值.

| Abstract: | In this paper, the theory background of the dampedoscillation closed-loop engineering identification method on object models is summarized. Experiments on pressure pneumatic control system equipment result in a simplified maths model. Emulation based on the model shows small parameter error and it is suitable in real system on-line identification. Therefore, it can form a kind of simple self-adaptive PID control systems. For some nonlinear real objects, by the use of the damped oscillation closed-loop identification method and restraining the range of the regulated parameter, the object model obtained is close to the normal operating mode and has engineering applicable values. |
