4、e courses emphasize design fundamentals and teamwork and culminate in the design of a significant device or system, usually of a multidisciplinary nature. This paper describes a capstone design project assigned to a team of eight electrical and computer engineering students at Kettering University i

5、n the fall term of 1998. The project consisted of the design, construction, and demonstration of a pulse width modulated (PWM) dc motor speed controller for application in a lightweight electric vehicle. The basic specifications at the outset of the project were: * The controller should operate over

6、 a range of voltages from 24 V to 48 V. * The controller should be able to handle a current load of at least 100 A rms. * PWM operation should be in the inaudible frequency range (recommended 20 kHz). * Under-voltage, over-current, and temperature protection must be employed. * Budgeted expenditures must not exceed $500.00. The design team was organized into groups of engineering specialists with each group assuming primary responsibilit
