Abstract
In this paper, black widow optimisation (BWO) algorithm-based proportional-integral-derivative (PID) controller is proposed for Riverol-Pilipovik (RP) water treatment plant. The plant is a two-input-two-output (TITO) system with two interacting loops, hence a decoupler is deployed to convert these interacting loops into non-interacting loops. PID controller is designed by formulating an integral-square-error (ISE) and minimising it. In this work, black widow optimisation (BWO) algorithm is used for minimising the ISE. The interval model of the RP water treatment plant is considered and the controller is designed for both lower interval as well as upper interval model by using BWO and Jaya algorithm. The results obtained affirm the fidelity of the proposed BWO-based PID controller. Further, the controller design is efficient and stable.
