Objective

• Make it as reference as Literature Review
• To know more about pH Controller

Content/Procedure

Previous Project

As the process to be controlled is highly nonlinear, the usual PI-type fuzzy controller is not able to control these systems adequately. To solve this problem, based on prior knowledge of the process, the pH neutralization process is divided into several fuzzy regions such as high-flow rate, medium-flow rate and low-flow rate. Then, a fuzzy logic controller is designed using random variable of pH value as input, giving adequate performance in all regions.

     One of the most critical problems in practical engineering design and implementation applications is the total cost and time constraint. Industrial control projects also are restricted by financial limitations especially in hardware.

Result/Analysis

• There are problem related about total cost, time and financial.
• For neutralization that have each rate need to fix it.
