Research on Efficiency Model of the Variable Hydraulic Pump Based on System Identification
For the complication and imprecision of the calculation of efficiency about variable hydraulic pump,based on system identification theory and thought of identification with the modeling,the general polynomial expression is proposed to describe the efficiency of variable hydraulic pumps and the functional relationship between parametric and to set up the model using the least square method of parameters identification,and calculation model of the efficiency is established as an example for a type of axial piston variable hydraulic pump,the model is verified by the experimental data,and its fitting accuracy is over 87%.
