the tuning of the PID gains is always a challenge in the state of the art of PID controller design. In other words, the main problem with a PID controller is the fact that the parameters of the PID controller must be adjusted properly to meet desired performance. This problem becomes more important when
(s) is the controller transfer function. PID controllers used in industry may not have the same structure though (Astrom and Hagglund, 1995; Goodwin et al., 2001; Astrom, 1996; Clair, 2000). Series PID (PIDS) There is a slightly different version of the PID controller, known as the “series” or “interacting” controller.
The conventional PID controller is replaced by Ziegler-Nichols tuning PID controller to make them more general and to achieve the minimum steady state error, also to improve the other dynamic behaviour (Rajkumar, A. Patra, Vijay, 2012). Most process industries used PID controller to control the plant (system) for the desired set point. PID

The PID controller is the standard controller used at the lowest levels in process control conﬁgurations. It is also often used at higher levels and in many other engineering areas. Together with a process section, the PID controller forms the basic feedback loop, see Figure 1. The major input signals to the controller are setpoint
PID controller has been extensively used in industries since 1940s and still the most often implemented controller today. The PID controller can be found in many application areas: petroleum processing, steam generation, polyme r processing, chemical industries, robotics, unmanned aerial vehicles (UAVs) and many more.

Auto-tuners for PID Controllers Despite all the progress in advanced control, the PID remains the most popular controller. Any stable system can be controlled with an integrating controller; performance can be increased by adding proportional and derivative action. There is ample evidence that many manually tuned PID controllers do not work well.

controller possibly unstable. To strike a balance between tight control and smoothness of downstream flow, the final tuning PID parameters are somewhat detuned to be: P = 2, I = 40 min, D = 0 min, Gap gain = 0.5, Gap high/low = 2%. If the level is within 2% of the SP, the gap action detunes the controller action by
