In order to increase the performance of the Ward Leonard layout system with H∞ optimal control synthesis and H∞ optimal control synthesis via. γ-iteration controllers are used. The open loop response of the Ward Leonard layout system shows that the system needs to be improved. Comparison of the Ward Leonard layout system with H∞ optimal control synthesis and H∞ optimal control synthesis via. γ-iteration controllers to track a desired step speed input have been done. Finally, the comparative simulation results prove the effectiveness of the proposed Ward Leonard layout system with H∞ optimal control synthesis controller in improving the percentage overshoot and the settling time.} }
