In this paper, the authors improving the performance of the direct current drive system by optimizing the efficiency of separately excited DC motor based on loss model under different loading conditions. The separately excited DC motor efficiency controller designed to determine the optimal field current which produces the optimal flux depending on the mechanical load torque applied to motor shaft. A Fuzzy logic controller is used to maintain a motor speed at predetermined level running at different load torque. The DC drive system is modeled and simulated using Matlab Simulink toolbox and the results are validated by comparing power parameters of both open loop and optimal fuzzy drive systems.
