Abstract

Nature inspired algorithms are among the most potent and robust algorithms for optimization for solving the real life problems. This paper introduces the Bat algorithm for the optimization based design of the PID controllers. The optimized PID controller has been implemented for liquid level control system which finds a wide application in petrochemical, food processing, and water treatment industries. The quality of control directly affects the quality of products and safety of the process. The simulations indicate the eminence of BA over classical methods of PID tuning.
