This video presentation was produced as part of Digital Systems Implementation, a fourth year course in the Department of Electrical and Computer Engineering at the University of Manitoba in Winnipeg, MB, Canada.
Direct current control in the dq frame is used to control motor output torque (implemented in floating point hardware in the FPGA). A PI based speed control loop is added to control motor speed. This is implemented in C code running on an instantiated Nios II processor. The GUI runs on a PC and communicates with the drive via an RS232 interface.
