Abstract

Developing the technology to drive the electric motors for the NASA hybrid-electric and all electric air vehicle efforts contributes to NASA’s goal of reducing fuel consumed by half and reducing emissions. Proportional-Integral-Derivative (PID) control scheme of electric motors is a common method of control. In order to compose a robust PID control program, it is necessary to use a motor controller with software that is predictable and customizable. A Graphical User Interface (GUI) was developed to help control the motor and evaluate the speed, torque, current and voltage readings from the motor. The GUI included numerical information and an oscilloscope for visual reference. The information collected from the GUI can be exported to an excel file and evaluated. The fine tuning of a PID motor control system requires knowledge of the inductance and resistance of the motor. The inductance and resistance of several different permanent magnet synchronous motors (PMSM) were measured using a laboratory grade Inductance, Capacitance and Resistance (LCR) meter. LCR values used in a comparative study with motor control software with built in automatic parameter identification software in the input for validation. The information gathered from evaluations like these will give a better understanding towards the development of electric and hybrid-electric air vehicles.
