Gelatinization and Frying Temperatures Stabilization of a ‘Garri’ Frying Machine Using a PID Microcontroller-Matlabsimulink
Journal Title: Scholars Journal of Engineering and Technology - Year 2017, Vol 5, Issue 6
Abstract
PID micro controller are used with the objective of controlling the gelatinization temperature and the frying temperature of a garri frying machine to improve the quality and dietary standard of garri with little or no lumps formation and no significant sign of being charred . Most research works on the design of garri frying and processing are limited with the problem of temperature stabilization or control, hence, this flexible design will help to stabilize gelatinization and frying temperatures within a range of( 70-90)oC and (180-200)oC respectively. Mathematical models of the gelatinization and frying chambers with their respective actuators were developed with the use of matlab simulink using Zeigler-Nichol tuning method to the PID parameters for a desired response of the systems when subjected to a unit step input. The schematic model and animated simulation was done to compliment and validate the system performance at these temperatures in the two chambers using a knowledge soft ware base –Proteus. A set of optimal parameters were obtained with using Zeigler Nicholas tuning after several iterations and simulation to have a desirable improvement with a focus on the settling time of 29.8seconds and 26.7seconds for drying and gelatiniztion process respectively to improve the robustness and stability of the entire system. Keywords: PID Controller, Zeigler-Nichol tuning method, gelatinization and frying temperature control, ‘garri’ frying machine. Simulation with matlabsimulink and proteus.
