Maintaining track tension in tracked vehicles minimizes the excessive load on the tracks and prevents the<br/> peal-off of tracks from the road-wheel, and adequately guarantees the stable and improved driving of the<br/> tracked vehicles. However, the track tension cannot be easily measured due to the limitation in the sensor<br/> technology, harsh environment, etc. In this study, the track tension is estimated in real-time from the<br/> measurable signals of tracked vehicles and controlled based on a fuzzy logic controller. The proposed control<br/> system is implemented on tracked vehicles and its performance is evaluated under various driving conditions.

DTTS(Dynamic Track Tensioning System) system requires robust control performance for the various maneuvering tasks. However, it is very difficult to tune the controller gains in experiments. In this paper, the hydraulic unit is modeled and constructed into the DTTS control module in Matlab/Simulink. The control module is interfaced to the vehicle dynamics module so that the control performance of the DTTS system can be evaluated in simulations. The dynamics data and control input data are exchanged between two modules at each control time-step. The gains in the fuzzy-logic controller are varied and the control performance is evaluated in simulations. The proposed simulation tool can be very useful for the gain tuning of track tension controller in tracked vehicles
