During the Electric Discharge Machining process, ensuring that there is the appropriate amount of spark gap between
the tool and the workpiece is one of the most important factors in determining how well the machine will perform. With the
assistance of Simulink models, this work will compare the effects of a Bang-Bang Controller, a Proportional-Integral-Derivative
(PID) Controller, and a Linear Quadratic Regulator (LQR) Controller on a dynamic EDM process. Through the use of
simulation, it was possible to observe the effectiveness of each controller in correctly maintaining the spark gap distance. This
effectiveness was then used to determine the approximate values by which the controller could be implemented on the physical
EDM setup
