Optimisation of EDM Process for Water Purification

Abstract

This paper discusses the process of water purification from harmful impurities by using electrical discharge machining (EDM) metal balls in an aqueous solution. The mathematical model has been developed for the water purification process. The control action was optimised using a mathematical model. To achieve the optimisation an extremal controller has been used. As a result of the process water purification optimisation, the electricity cost was minimized.
