Abstract The dynamic behavior of hydro-static transmission
(HST) systems is studied experimentally and theoretically
to formulate a linearized mathematical model of the
HST system and a recursive identification model is then
proposed. A computer-controlled test rig is developed and
the system state responses are measured. The results
obtained from the experimental work and the linearized
models are used to build a recursive identification model in
order to identify the system under study. Furthermore,
comparisons among the experimental, simulated, and
identified results are presented. These results show that
recursive identification models are powerful tools that can
be used for the identification and analysis of HST. Finally,
parameter variations of the volume displacement and the
motor torque are introduced to the system in order to study
their effect on pressure and hydraulic motor speed.
