摘要：
The paper presents the identification procedure for obtaining of transfer function model of an electrohydraulic power steering systems for low speed mobile machines. The single-input, multiple-output (SIMO) system model was obtained based on experimentally measured data from a laboratory test bench steering system. Proportional spool valve position, flow rate supply and steering cylinder position output variables are measured in an open-loop identification experiment. The identified SIMO model is validated with independent data-set and reduced to 3rd order transfer functions. The resulting model will serve for further work on the synthesis of multivariable embedded controllers for the electrohydraulic power steering systems.
