水泵全性能曲线无假定建模电脑仿真

Non-assumed Modeling Computer Simulation of Universal Complete Pump Characteristics

投影寻踪回归(PPR)无假定建模电脑仿真技术,对水泵Suter通用全性能曲线,可以不分割进行整体建模和仿真,其精度达到和超过了二次多项式分割成4个矩形区域建模仿真的精度。证实了PPR无假定建模的可靠性,而且方法和过程则更为简便,也为水泵Suter通用全性能曲线的电脑仿真提供了新的途径。

The non-assumed modeling with projection pursuit regression （PPR） was used in Suter complete pump characteristics, which can be modeled and simulated without division. The accuracy of this method has reached and exceeded that of quadratic multinomial which divides into four rectangular regions. The results show that the non-assumed modeling with PPR is reliable and simple as well as the method is more easier than other methods. So it is a new way to simulate Suter complete pump characteristics.
