Abstract
Electrical discharge machining (EDM) has experienced steady growth in engineering applications since its emergence. This paper has presented positioning control of electrical discharge machining (EDM) device for improved transient response performance. A model dynamic of a DC servomotor responsible for positioning tool electrode on a workpiece was obtained. The controlled variable is the angular shaft position which was made the output of the process in the model transfer function. A proportional integral and derivative (PID) compensator was designed using robust response time tuning method with interactive, adjustable performance and robustness of the Matlab control tool box. The designed compensator was integrated with the servomotor to form a closed loop control system. Simulations were performed for uncompensated and compensated conditions of the machining process. The results obtained indicated that with the compensator in the loop, the transient response performance of the servo positioning was largely improved.
