摘要
对泵站进行调速控制时,为了更好地节能,必须考虑水泵参数的时变性。本文研究在信息不充分的条件下,并联水泵机组的有约束非线性参数辨识问题。提出一种校正式逐次线性逼近法,有效地解决了问题。接着,采用分级寻优决策,实现了泵站调速的自适应控制。
The time-variation of the (?)mp pa(?)ameters must be considered when using speed variation in pump station for energy saving.This paper diseusses a non-linear bounded identification problem of parallel-pumps under the circumstances information is not suf- ficient.An alternate linear-approach method with correction is advanced for solution of this problem.Based on identification an adaptive control method is obtained by using hierar- chical optimisation of pump station.
