| Summary: | The most common type of controller in the chemical process industries is a proportional, integral, and derivative (PID) controller because it is simple, easy to operate, and successful in operation. The regulation of speed, temperature, flow, pressure, and other process variables can all be controlled by using a PID controller. The purpose of this study is to run an open loop test to obtain a process response curve upon which Response Rate (RR), Dead Time (Td) and Time Constant (Tc) are analyzed to confirm the ideal tangential method for the process control loop system. There are several different methods that are used in the process such as Normal Tangent Method, Reformulated Tangent Method and Two-point Method. The values from the three methods are then calculated using Ziegler Nichols tuning rule to be used for further steps. The main objective of the study is to compare among the three methods that will give the better and desired control performance. Settling time and Integral Absolute Error (IAE) has been used as the
criterion for the comparison. |
