Abstract

Solar photovoltaic (PV) is a technology that is often used in the agricultural industry as an alternative source of electrical energy to power up simple appliances throughout the farm. This technology however, are still far from the norm for Malaysian farmers. By looking at the mushroom agricultural industry, the main concern of mushroom growers in Malaysia when growing their mushroom is to control the temperature inside the mushroom growing hall as they are lacking in efficient method to control it and has to rely on manual unconventional method. This thesis aims to study and develop a working simulation of the PV powered temperature control system. It used the oyster mushroom as the preferred crop due to the growth in its market demand. A Matlab/Simulink tool was used to create a working model simulation to analyse the system performance in maintaining an optimal temperature of 28℃. The main components of the simulation are in the mathematical model used for the mushroom house subsystem which was designed based on the energy balance equations. The subsystem was then connected to a series of Simscape electrical components that produced air mass flowrate as an input to the mushroom house subsystem to complete its energy balance calculation. A series of simulation was run for an ON, OFF, and ON-OFF system setting and the result of the room temperature was analysed to study their behavioural pattern. The simulation results showed that the ON-OFF setting managed to control the room temperature under a range of 26.03℃ – 29.99℃ with standard deviation of 0.949634. The simulation was then compared with a fuzzy logic control system that maintained an adaptive and precise room temperature of around ±28.7℃ with a standard deviation of 0.633798. The simulation results concluded that a working solar-powered temperature control system for the oyster mushroom house is successfully developed
