Adaptive PID Control of an Industrial Process Based on IMC Tuning Method

An industrial process should has real-time response and good performance in tracking desired values. For achieving these purposes is used discretization of differential equations of system. Also with using a mathematical method, the gain and time constants of system are obtained based on inputs and outputs of process. Furthermore, In order to find the approximate coefficients for adaptive PID controller, the IMC method is applied. The results of this method which is utilized in an industrial process, flow control of pipeline, has excellent response.
