The self-tuning fuzzy PID to regulate the steam temperature in real-time process

摘要

Conventional steam distillation is lack of control in order to satisfy the process requirement. In steam distillation process is regarded as the most significant parameter that contributes to the amount of output yield and quality of oil. An appropriate controller needs to integrate to the plant in order to regulate the steam temperature at desired or appropriate condition. This study demonstrated several controllers which are self-tuning fuzzy PID (STFPID) and hybrid fuzzy PD with PID (HFPPID) controller in order to improve the output controller performance compared to the conventional PID controller. Initially, this controller is proposed to reduce the overshoot of output, improve the rise and settling time and reduce a steady-state error of the step response. The performance from demonstrated controller shows that STFPID has the ability to improve process rise time, settling time and reduce of steady-state error and process overshoot compared to others.
