Advanced control techniques for process industries have become more damaging due to the increasing complexity of the processes and stricter requirements for the product quality and environmental factors. Intelligent based control approach has become a trend for advanced control techniques mainly neural network and fuzzy logic. Control of pH neutralization process is a challenging process because its inherent strong nonlinearity. Failure to control the process will have significant impact to the environment. In this project, a mathematical model of pH neutralization with specific plant parameters is developed. The model of the process and its simulation are implemented in MATLAB application. The model obtained will be used for application of classic PID and intelligent based fuzzy logic controller for evaluation. Each controller performances are analyzed for comparison based on preset control performance criteria
