几种液压AGC方式的图形化仿真比较

Simulation and comparison of several hydraulic AGC systems

为提高计算机进行轧制仿真时的结构灵活性和扩展方便性,以控制系统常用的软件MATLAB/Simulink为平台,将主要轧制设备建立传递函数模型,用有相应输入输出端口的简单框图表示,类似实际设备可以自由调度组合,搭建出不同控制系统,从而开发出既便于独立建模研究又易于构建不同控制方案的轧制形象化仿真方法.通过输入同种原始条件,对几种液压AGC系统进行了仿真比较,结果表明动态设定AGC响应更好.

In order to improve the flexibility of assembly and expansion in simulation of rolling process on computer, MATLAB/Simulink was used as a basic platform, which is often adopted in control systems. A transfer function model building for main rolling equipment was denoted by the simple block diagram with input and output interface, and dispatched and constituted freely as practice equipment, then various control systems was built. The visualize simulation method for rolling was developed, which can study the model independently and assemble different control schemes easily. Several hydraulic AGC systems were simulated under the same initial condition, and the result shows that the dynamic set AGC is more steadily.
