Tuning of Distillation Column Control

Distillation column is one of the most important equipment in a chemical industry. It is quite a challenge to control both the composition of the bottom and top product without affecting the composition of one another. By designing a good controller and a good tuning for a controller, a distillation column can be controlled efficiently and a product with a high quality can be obtained. A few methods are applied in this project which is by first designing a controller which is a PID controller and a MPC controller. Once the designing of the controller is done, an algorithm is developed to make sure that the tuning of distillation column control can be done efficiently. Then, the controller tuning setting is tested using matlab and the result of each approach is compared and the best result is selected to control the distillation column. Lastly, a performance evaluation is done in order to make sure that the controller tuning does not damage the valve. Therefore, by studying on tuning of distillation column control the composition of the bottom and the top product can be control and the product of a distillation column can be obtain according to the desired value
