| contents | Motorized Valve or Motor Operated Valve (MOV) is an important item of Plant & Piping system. These valves are generally of wide size range and are used for different applications such as Pump discharge, process industries, power generation stations oil and gas, and control of wide range of fluid flow. The problems of MOV are usually Position Overshoot which could be caused as a result of aggressive tuning of the controllers, Stiction which is a combination of words stick and friction. This term is a condition that holds the valve in a particular condition and sticks it there, not allowing it to move. In this paper, existence of stiction was identified through mathematical models. Proportional controller was introduced to overcome the instability to attain steady state. Results shown, indicates that stiction causes drag, external force and delay time in output delivery. In conclusion, a model based stiction control of a motorized valve was achieved. |
