Abstract

This project aims to optinrize the efficiency as the dependent variable with voltage and speed as the independent variables of DC motor by using optimization process. DC motor is used because it has high energy and power to carry loads in addition to widespread use in the industries sector. Furthermore, this research will use two methods which are Nelder­ Mead method and Powell's method to get the optimum efficiency. Finally, this method will be compared to obtain which one as the best estimation of the optimum efficiency. As conclusion the values of voltages in Powell's and Neider Mead are different and the values of angular velocity (co) also different. The minimum efficiency result of Nelder-Mead method is 0.01893 with the values ofvoltage 155V and angular velocity (co) 193.747rd/s. Powell's method efficiency is 0.01895 with the values of voltage 155.011V and angular velocity (co), 193.7677rd/s which makes it the Nelder-Mead method is better. However, the 1
