Hi, I'm Bill. I'm a software developer with a passion for making and electronics. I do a lot of things and here is where I document my learning in order to be able to inspire other people to make ...

A quadrature encoder uses two output channels offset in phase to detect both direction and position with greater precision.

Abstract: To suppress the torque ripple for smooth speed control of electric drives, active disturbance rejection (ADR) controller based on generalized integrator (GI) extended state observer (ESO) ...

Abstract: The traditional DTC method directly controls the torque and flux linkage without model calculation, which is beneficial to restraining torque ripples. However, the LRSRM not only provides ...

This Arduino flight controller is designed for controlling a drone using an ESP32 microcontroller, various sensors, and PID control loops. It utilizes an NRF24L01 radio module for communication with a ...
