Design of Brush DC Motor’s Speed Controller Using PI Method with Adjusted Hydrogen Fuel Feed on The PEMFC

Abstract

Hydrogen is one of the alternate way that become a solution of the crisis of energy problems. Fuel cell transform the hydrogen into electric power, heat, and water. The power that was made by the fuel cell can be used for a lot of things, and transportation is one of them. This research main point is to make a design of a speed controller for a DC motor as a main object using the power that was created by fuel cell. The controller is a system that will increase the efficiency of the hydrogen used ,as a main supply, with controlling the flow rate of hydrogen that flowed into the fuel cell in order to avoid the over flowing of hydrogen that will cause the hydrogen wasted. The controller will also boost the DC motor’s response. To conduct the research, the method that is the most suitable for the case is PI control system that will boosted the transient response from the system which stands from a proportional, derivative, and integral parameters that will be tuned by using a root-locus method with the purpose to make a system that has a quick rise time and low %overshoot that will make the system has rise time=10.1s, settling time=66s, peak time = 40.9s, % Overshoot=8.66%, steady state=1 as the transient response’s result.
