Design Of Controllers For Flow Process In Labview

Abstract: Flow is the most significant parameter that is measured in process industry. In flow process set point tracing is the most important algorithm which is obtained using computing algorithm like PID, IMC, IMC-PID. IMC and IMC-PID controller characteristics is compared with conventional PID controller. To obtain the better performance to bring the process in desired set point. In process control application, spontaneous controllers are introduced. The different controllers are included in this paper (PID, IMC, IMC-PID). The most widely used trade controller is the PID (Proportional-Integral-Derivative) controller. Here the tuning of PID controller is done using Cohen coon method. The Internal Model Control (IMC)-based approach for controller design is one of them using IMC and its equivalent IMC based PID to be used in control applications in industries. IMC-PID is used for tracking set point for unsteady process.
