PWMiga

PWMiga is a modular framework and hardware platform for generating and optimizing pulse-width modulation (PWM) signals used in motor control, power electronics, and related embedded systems. It combines a real-time PWM generator with an adaptive control layer that tunes duty cycles to track target performance metrics such as speed, torque, or voltage efficiency.

The architecture centers on a real-time core implemented in microcontrollers or FPGAs, capable of generating high-resolution PWM with synchronized timing across multiple channels. The control layer supports traditional PID paradigms and can incorporate predictive or learning-based adjustments to compensate for nonlinearity, load changes, or thermal effects. A software interface provides configuration, monitoring, and logging, while safety and fault-handling modules help prevent unsafe operation.

Key features include multi-channel PWM generation, fine-grained timing resolution, hardware-accelerated duty-cycle updates, and plug-in control modules. PWMiga emphasizes portability, offering both firmware templates for common MCUs and open-source driver stacks for popular development boards. It also supports hardware-in-the-loop testing and simulation tooling to validate control strategies before deployment.

Applications span robotics, CNC machinery, electric propulsion, and power-supply regulation, where precise, efficient PWM control improves performance and longevity. The project is maintained as an open-source initiative with community contributions and reference designs, though real-world adoption varies by industry due to safety, certification, and integration requirements.
