Abstract: Synchronous pulsewidth modulation (PWM) scheme is more attractive than asynchronous one in low switching to fundamental frequency ratios, for its better harmonic spectrum. But, when a ...

Abstract: We derive Fourier series expressions for modeling analog closed-loop PWM class D amplifiers. Based on our derived expressions, we are able to analyze the mechanisms of several nonlinearities ...

This project demonstrates a minimal, high-performance, and low-power application for the Artery AT32F421 microcontroller. It is written in pure C with direct register access, avoiding vendor HAL ...

PID控制应该算是非常古老而且应用非常广泛的控制算法了，小到热水壶温度控制，大到控制无人机的飞行姿态和飞行速度等等。 在电机控制中，PID算法用得尤为常见。 在电机控制中，我们给电机输出的是一个PWM占空比的数值。 上图中的目标位置一般我们可以 ...

This repository contains the mechanical CAD, drawings and embedded firmware for a small 2-axis/3-phase BLDC camera gimbal prototype. The project uses an STM32G431 MCU to read an MPU6050 IMU, an ...
