Home built rig showing position control of a large 350W dc Motor. uses a quad detector for position of the shaft and a second quad detector for the setpoint. The H bridge used is a DBH-01B Smart Car 50A Dual Channel one available from Ali-Express and the motor can be almost any motor as long as its current isn't over the rating of the H bridge. I use a bicycle dc motor. Has a PID controller built from scratch (not a NI vi one). Uses the FPGA and the host controller.
