Abstract: This article presents a sensorless control strategy based on an improved sliding mode speed controller (SMSC) and sliding mode position observer (SMPO) for switched reluctance motor (SRM).

Abstract: In this article, an observer-based prescribed performance speed control method is proposed for permanent magnet synchronous motors. A transformed speed ...

Electrical energy is no longer treated as an unlimited utility. Every watt consumed has a cost impact, an efficiency implication, and in many cases a safety consequence. A smart grid in IoT is not a ...

This project implements an encoder-based measurement system and PID control for motor speed using Arduino. It includes pulse reading, speed calculation, and closed-loop PID control with simulation ...
