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 ...

Many cities, including San Francisco and Los Angeles, limit the amount a landlord can raise the rent each year — a policy known as rent control. But for nearly 30 years, California has imposed limits ...
