Abstract
The application of precision agriculture in farming practices results in higher yield and productivity with lower costs. Several works have applied this concept to poultry farming to reduce human involvement, stress, fatigue, wastage of poultry feed and provide a high return on investment. A number of these systems lack control techniques to improve the system performance. A few works exist that implemented control techniques to improve system response, but different systems were implemented and therefore, a comparison cannot be made. In this paper the performance comparison of the Fuzzy Logic Controller (FLC) and the PID Controller on the Poultry Feed Dispensing System was evaluated in a quest to determine the more efficient and effective controller. The system was modelled and simulated using MATLAB SIMULINK and the performance was evaluated based on the rise time, settling time, overshoot and Integrated Absolute Error (IAE). The results showed that the system implemented with the PID and FLC performed better than the system without a control technique. The PID gave a faster system response than the FLC in the solid feed subsystem with a difference in rise time, settling time and IAE of 9.72 seconds, 11.68 seconds and 4.74 respectively. The FLC performed better in the liquid feed subsystem with a difference in rise time, settling time, overshoot and IAE of 9.22 seconds, 33.07 seconds, 13.92% and 7.18 respectively. This shows that the PID controller is more suitable in the solid feed subsystem and the FLC is more effective in the liquid feed subsystem.

Due to the shortcomings of the works presented above such as absence of control techniques, undesirable system response, susceptibility to instability and disturbances, this paper presents a performance evaluation of a poultry feeding system implemented with a Fuzzy Logic Controller (FLC) and a PID controller in a quest to determine the more suitable, effective and efficient control technique in the poultry feed dispensing system
The poultry feed dispensing system was simulated with a fuzzy logic controller and a PID controller
Summary
PRECISION AGRICULTURE is an information and technology based farm management practice. These pitfalls result in poultry farming being carried out in the tropics at a high cost with a little return on investment [5] Due to these shortcomings, there is a need to employ the principles of precision agriculture to develop systems that automate the process of poultry feeding. Proportional Integral and Derivative controllers have been around for a very long time, and despite being used in industrial control applications for a while, they are still widely used today. This is due to their simplicity, low cost, robustness and ease of re-tuning [8], [13]. The equation of a PID controller can be represented as shown in equation 1
