Internal disturbances of a working globe valves come in three variants. The variants are the breakaway point, the stuck point, and the moving friction point. These disturbances inhibit the free flow of fluid in a working globe valve system. The natures of these disturbances are modeled mathematically and simulated using SIMULINK for better understanding. An Anti-windup Proportional Integral Derivative Controller (APIDC) was introduced to control the operation of a globe valve due to the saturation effect of the conventional PID controller. The results obtained for a disturbance-free working globe valve system has an overshoot of 1.40 with a unit step input function and settling time of 0.025 min. while an overshoot of 1.45 with a unit step input function and a settling time of 0.0375 min. was recorded for a working globe valve system with disturbances. This work presents an improved technique to handle the internal disturbances of a working globe valve.
