| Summary: | This project is about automation system design implementation on Nata de Coco leaching process. The dynamic behavior based control approach is implemented in this work. Initially, study on dynamic behavior of the liquid level system is done with mathematical modeling and simulations. The system is studied by considering three cases; single tank system, two tanks system and three tanks system. The water level system for Nata de Coco leaching process is designed by considering the case which the system has best dynamic behavior. Experiment is implemented to compare simulations results and experimental results of the dynamic behavior of liquid level system. For the study of pH control, experiment is also implemented. An automation system is proposed and a brief overview of the proposed automation system process is also included. The automation system is designed based on data obtained from experiment in this study. The prototype for Nata de Coco leaching process is fabricated. The automation system is implemented on the prototype. The dynamic behavior of the liquid level system is found to be highly non linear. The comparison of simulation results and experimental results validated both the simulation and experiment on liquid level system. The automation system is found to be operated on the basis of switching between on and off status of the valves at different time interval, and the on off switching time is obtained from experiments that had been done in this study. The dynamic behavior based control approach that has been used in this study has the advantage of low cost. |
