Abstract One main objective of this research project is to study the stabilization of the operation of Benfield solution (8.S) stage (in Talkha Il Fertilizer Company )by designing an appropriate control system for the level of (8.S) in the absorption tower. It is very important to construct a mathematical model which simulates the practical system construction and operation. In this model a proportional integral (PI) controller is designed to control the process. Both the continuos and discrete types are considered. The different techniques of ptimization are utilized to minimize the error performance using proportional integral control parameters (PI) to ensure that the system output tracks changes in the reference signal in an acceptably fast way. It is required to obtain a zero steady - state error following a step reference input. Both theoretical analysis and experimental studies result in a well accepted model with different system parameters. |
