Real Time Interfacing of a Transducer with a Non-Linear Process using Simulated Annealing

Abstract

Proportional Integral Derivative (PID) controller has become inevitable in the process control industries due to its simplicity and effectiveness, but the real challenge lies in tuning them to meet the expectations. Although a host of methods already exist there is still a need for an advanced system for tuning these controllers. Computational intelligence (CI) has caught the eye of the researchers due to its simplicity, low computational cost and good performance, makes it a possible choice for tuning of PID controllers, to increase their performance. A closed loop performance is achieved with few transducers and controllers which can support a stable and efficient process. This paper discusses in detail about the simulated annealing (SA) algorithm, a CI technique, and its implementation in PID tuning. Compared to other conventional PID tuning methods, the result shows that better performance can be achieved with the proposed method.
