摘要
上海南市水厂的中间提升泵房是其二期改造工程的重要环节。针对传统的PID算法计算复杂的缺点,提出了判断区间算法,该算法仅需进行简单的逻辑判断就可以得到液位的具体位置,并且得到相应的运行频率。在PLC上运行结果表明了这种基于判断区间算法的PID的正确性。采用该算法后,水厂的出水水质得到明显改善。
Pump house was an important part of Phase II project of Nanshi Water Plant of Shanghai Municipal Waterworks. Interval judgment algorithm was used due to the shortcomings of complexity of the traditional PID algorithm. Interval judgment algorithm only required simple logic judgment to get the specific location of the liquid level and frequency, so the computation could be simplified greatly. The results showed that this PID algorithm based on interval judgment run on the correctly. After using this algorithm, the water quality of effluent had been improved obviously.
