Abstract:
Currently, most industries in Ethiopia use steam for a variety of purposes, including sanitary and
pasteurization processes. This thesis shows how to use renewable energy instead of gas fuel for
steam generation in a factory and how to use an advanced controller to manage the temperature
level of the steam generator in a case study of the Bedele brewing factory. Currently, gas fuel is
used in this factory’s boiler plant, and steam temperature is controlled using a PID controller.
Because gas is a non-renewable energy source with high costs and environment affect, it is
preferable to replace it with a renewable energy source such as solar energy. Furthermore, in the
case of solar energy systems, advanced MPC controllers are preferred over PID controllers for
predict the next value.
This paper presents Model parabolic trough collector based on collected data to produce steam
for pasteurization plant in Bedele brewery factory. Here, apply PTC technology using solar
system. Additionally model MPC controller to supply fixed temperature of steam for
pasteurization plant. Here, MPC control the temperature of steam with respect to given set point
(413K). In this thesis, Analysis the performance of MPC interims of both steady state response
and transient response. According to the thesis steady state error almost approximates to zero and
preferable transient response result then PID controller. Therefore, MPC controller is more
advisable for this temperature controlling system in this Factory.
