This paper focuses on the estimation schemes of a viable position for timing belt
drives where the position of the carriage (load) is to be determined via reference models
receiving input from a position sensor attached to the actuator of the timin
g belt. A detailed
analysis of the transmission error sources is presented, and a number of relevant
mathematical models is developed using a priori knowledge of the process. This paper
demonstrates that such schemes are very effective when the drive system is not subjected
to external loads
and operating conditions do not change considerably i.e. ambient temperature, and
belt tension.
