Abstract
This thesis presents the modeling, design and control of the belt drive system in Finchawa sugar
factory.
Belt drives have been serving in this industry for a long period of time. Certain features of belt
drives such as slippage, tension fluctuations, and sliding of the belt on the pulleys lead to highly
nonlinear deformation, large rigid body motion, dynamical contact with sticking and slipping
zones and cyclic tension. In addition to these problems, in Finchawa sugar factory, the tracking
control mechanism of the belt drive system has many problems. The main problem is slow
response and lack of accuracy. This is because the control is manual with simple ON/OFF
control mechanism which is more difficult to obtain fast response and accurate tracking.
The performance of motion control for belt drives is important in many industrial fields and is
affected by these factors. PI control can improve performance specification of belt drive system
and result in a faster dynamic response and more accuracy.
Hence in this thesis, modeling of a linear belt-drive system and designing of PI controller for its
position and speed control mechanisms has been examined by changing the reference of the
system with the maximum steady state error of 0.0027% and good transient performance with
rise time less than 0.1 second.
Friction phenomena and position dependent elasticity of the belt was analyzed. The PI controller
has been designed for accurate speed and position control mechanism and was simulated on
MATLAB.
