Implementation of control system for hydrostatic transmission test rig
Hardware-in-loop Simulation
Project Course 2010 - Flumes Department - TMPM01
Introduction
Hydrostatic transmission is an efficient way of power transmission in off-highway
applications such as construction machines, forest machines etc. This concept enables us in
achieving higher speed/torque conversion range with lower power transmission losses.
This project deals with replacing of existing xPC target based control system in the
transmission test rig with a LabVIEW based target computer developed by Prevas.
Controllers from the previous works done on same hydrostatic test rig were taken and
analyzed. New controllers for the drive, transmission and load side of the test rig were
designed and implemented in Simulink and validated using co-simulation with AMESim .
Hardware connections were successfully tested by trial runs. When the target computer is
replaced, the controllers were implemented for the new target computer using Viking GUI.
Sensor signals coming from the rig were identified properly and control signals generated by
controllers were sent back to the rig.

Conclusion and future works
Drive side controller
3D look up plot for load side controller
Drive side controller was tested successfully. New interface
offers flexibility in changing controller parameters in real
time. Significant improvement in the new system is the
achieved better sampling rate of sensor signals. User manual
with step by step procedure of Viking GUI interfacing is
done. Future works include implementation of transmission
and load side controller in Viking GUI.
