Implementation of hybrid fuzzy-PID integrated anti-windup controller for steam distillation process / Haslizamri Md Shariff ... [et al.]

The proper of temperature control are very important and compulsory in order to achieve high quality of desired essential oils via the process of steam distillation technique. The regulation of temperature purposely to ensure that the desired temperature value reach the setpoint without deviate which; contribute to the quality of essential oil. The well-known of PID controller is always utilized in industrial process. Unfortunately, the PID has suffer when the integral action reach at the saturation region which; the integral action unable to unwind the system. In this wind-up situation, the system exhibits high overshoot (which is deviate from the setpoint) and take more longer time to reach the settling time, which is contribute to produce bad quality of essential oil. To improve the situation the PID will be integrated with anti-windup system in effort to diminish the system overshoot and settling time. In addition, the PID plus anti-windup (PIDAW) system will be integrated with Fuzzy Logic controller in order to enhance the system performance. The Hybrid Fuzzy-PID plus Anti-Windup (HFPIDAW) controller is capable to control the time-varying of steam distillation process which; reveal the better simulation result in step test, set point tracking, load disturbance test and performance index compared to classical PID controller. Based on the simulation result, the modification of PIDAW and HFPIDAW controllers is able to contribute an ideas to industrial practitioner to design the controller in real-time process.
