His 11 mph over the speed limit could have been 10 mph, which falls within the grace range and wouldn’t prompt a citation. He took that argument to the DMV, which is the first appeal, all the way ...

Abstract: This paper proposes a sensorless speed control method for brushed dc motors that extends the usable speed estimation range by combining current-ripple analysis with high-frequency signal ...

Abstract: Traditional proportional integral derivative (PID) falls short for precise control of DC motor speed under changing conditions. This paper presents a novel FPGA based IP (intellectual ...
