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 ...

The importance of motor trajectory profiles and how they’re used in brushless DC (BLDC) motor control to minimize vibration and smooth out other performance issues. Why the PID loop is the most widely ...

WASHINGTON — A small but mighty group of neighbors in Capitol Hill is trying something new to battle mosquitoes this spring and summer, and their arsenal doesn't include harmful sprays or pesticides.

How brushless DC motors use electronic commutation to maximize efficiency and ensure smooth and stable motion. Compare trapezoidal, sinusoidal, and sensorless commutation techniques, including key ...

They’re in a rat race to clean up their city — and have resorted to pill pushing. Washington, DC is trying to crack down on its overpopulation of vermin by giving them birth control. DC Health plans ...

If you spend any time in D.C., you know rats are a problem. "They be in the dumpsters. They be running in groups, like, two, three — a few too many," one man told News4. Another resident said said ...

I performed the simulation of speed control of a three-phase induction motor using MATLAB/Simulink. Three-phase induction motors are widely used in industries due to their simple construction, ...

A ground stop was issued at BWI and other airports in the DC region on Friday, according to the Federal Aviation Administration (FAA). The stop was was a result of a strong smell at the Potomac ...

Bryant Reed joined WJZ as an Anchor/Reporter in December 2025. You can find him behind the desk on weekend evenings and out in your communities during the week. Before calling the Charm City home, ...

The number doctors use to demarcate hypertension keeps going down, a trend applauded by many experts, who point to studies linking high blood pressure and dementia. By Paula Span The patient initially ...

Passengers at three airports in the Washington, DC, area faced significant delays after a ground stop was issued Friday afternoon due to an equipment outage, according to the FAA and Transportation ...

Vector Control, also known as Field Oriented Control or FOC is an AC motor control scheme that enables fine-grained control over a connected motor, through the precise control of its phases. In a ...
