摘要
介绍以PCT-Ⅲ型过程控制设备为对象,以组态王软件为平台,对水位实现在线预测控制.根据理论给定液位与通过牛顿7017模块实际采集液位作比较,应用优化算法,先预测下一步的液位,然后进行比较计算修正在线控制液位,使液位按照预定的轨迹到达给定液位.实验证明预测控制水位响应速度快,相对PID控制来说没有超调,比较精确,得到满意的控制效果.
Based on King View, the water level of single case is controlled by the single step predictive command. In the method, it need not understand inner mechanism. And it is very easy to construct a model. By experiments, it shows that the predictive control is more accurate than PID control. The speed of response is very rapid. And there is no overshooting. The effect is satisfying.
