In extracting the essential oils, some of the influential factors need to be considered which can affect the yield and quality of the oils. Many studies have performed on several influential parameters and dictated that the temperature of extraction plays an important parameter that can give large effect on yield and quality. In order to regulate the temperature, a suitable controller is required...
The implementation of PSO as an optimization algorithm in finding the optimal values of PID's parameters has attracted a significant interest among researchers. One of the important parameters in PSO algorithm is inertia weight (ω) which directly affects the percentage of previous velocity used in determining the next position of particles. A high value of ω will force the particles to fly with a...
This paper presents a fuzzy logic controller (FLC) that has been implemented to control the steam temperature in steam distillation for the extraction oil. The objective of this research is to implement the ARMAX model structure and to design the typical controller using FLC to control the steam temperature as a controlled parameter. Temperature regulation is an importance factor to avoid the degradation...
Controlling a temperature for a large system is not an easy task, the lag is big and the overshoot is high. The conventional method of controlling this kind of process is not capable of giving satisfactory result. In this paper the implementation of Fuzzy Logic controller with Smith Predictor is an alternative to control this system. First order plus dead time model (FOPDT) is used for simulation...
This paper describes the development of interfacing system for glycerin bleaching process. The system is used to monitor and control the temperature and pH of the glycerin. The methodology includes the development of a monitoring and control system based on the use of simple data acquisition hardware module and software tools. The system outlined permits the user to access sensors or control system...
