| Abstract: | A new method of characteristic curve(e.g.power isogram,efficiency isogram, combination isogram etc.,) drawing for hydraulic pumps and hydraulic motors was introduced.This approach deals with the characteristic curve of hydraulic pumps and hydraulic motors using MLS.Compared with least square(LS),MLS has a high accuracy and large coverage.A curve drawing example compiled in MATLAB was given. |
