炉温滑模变结构控制系统的研究

A Research of Stove Temperature SlidingMode Variable Structure Control System

针对ＧＪ型光辐射加热炉在对不同材料加热时，其数学模型参数变化范围较大的特点，提出了采用滑模变结构控制代替常规ＰＩＤ控制的方法并对炉温变结构控制系统进行了仿真研究研究结果表明，采用变结构控制的炉温控制系统，不仅有很好的动态特性，而且具有较强的鲁棒性，对对象参数摄动具有很好的自适应能力。

When GJ type ray radiation stove heats different material, the controlled plant parameters vary greatly In accordance with this characteristic, a way is presented that replace the conventional PID control by the sliding mode variable structure control(VSC), and the simulation is done for the stove temperaturc VSC system The result shows that stove tempereture VSC system has not only better dynamic property, but also stronger robustners, and better self-adaptation for plant parameters variation This will extend the application of thenay radiation stove
