bldc-strip ========== Firmware for OpenBLDC "Strip" (STM32F103). ## Project description Bldc-strip is an open-source project aiming to design an ESC (electronic speed controller) for brushless dc motors. The control software is concurrently developed with a motor controller [hardware](https://github.com/joewa/open-bldc-hardware/tree/master/strip/v0.2) and [simulation models](https://github.com/joewa/open-bldc-modelica) which are used to investigate and test the control algorithms before/while they are implemented to the real controller software and hardware. It is designed to provide a better ESC for the control of small multi-rotor aircraft but should also fit other applications. ## Features - [x] Open-source control software for STM32F103 32bit microcontroller using [ChibiOS](http://www.chibios.org). - [x] Sensorless 6-step control method for brushless motors. - [x] Open loop voltage control to provide (almost) linear "brushed-motor-like" characteristics which is often requested by control systems engineers. - [x] High frequency PWM from 40 to 200 kHz enabling proper operation of some very small and fast motors. - [x] Dedicated control methods for fast, slow and very slow to zero rotation speed. - [x] Seamless 4-quadrant operation with regenerative braking. - [x] Smooth change of rotation direction. - [x] Closed loop sensorless position control (prove of concept) - [ ] Catch start of a rotation motor - [ ] Adequate protection functions: - [ ] limitation of motor current - [ ] limitation of input current - [ ] seperate limit for regenerative current - [ ] limitation of reference duty cycle command that would result in a current limitation - [ ] Software watchdog - [x] Command/control interface via UART - [ ] Command/control interface via CAN-bus ## Dependencies and references Designed and tested with the [OpenBLDC "Strip" V0.2 ESC](https://github.com/joewa/open-bldc-hardware/tree/master/strip/v0.2). Using [ChibiOS Real-Time Operating System](http://www.chibios.org). Multi-physics, open-source [Modelica simulation models](https://github.com/joewa/open-bldc-modelica) are designed to investigate appropriate motor control methods. In the future, they may be merged with this repository. Demo video on [YouTube](https://youtu.be/5QIjhmtY5ok) and [Vimeo](https://vimeo.com/124761289). Overview of sensorless 6-step control methods.
