- reduced FOC computational complexity by up to 20%, from 85% (old) to 65% (new)
- updated Field Weakening by allowing more freedom set-up: field weakening blended in the input fully, partially blended, or fully outside the input range
- major improvemets on current and speed limitations. It allows seemless limitation protection -> very happy with the result
Sinusoidal Control Type is now available is this branch. To select it go in config.h and change CTRL_TYP_SEL to 1. By default FOC control type is selcted.
Note: SPEED and TORQUE modes are not available for Sinusoidal control type.
The firmware allows now to set higher currents than 15 A/motor.
NOTE: You can change this limit at your own risk. I do not take any responsability if your boards gets damaged.
Major:
• all PI controllers with Back-calculation replaced with PI controllers with Clamping to reduce the number of parameters and simplify calculations
Minor:
• fixed the ADC calibration for potetiometer input when ADCx_MIN > 0
• fixed bug: small shock at initialization when current limit I_MOT_MAX is set very small e.g. 1 A
Major:
- Issue #3: added raw ADC1, ADC2 values to the setScopeChannel
- Issue #4: added functionality for joystick control. Middle resting potis are now supported (by default it is enabled)
- Issue #6: implemented that board does not power-off after a software reset due to flashing
- added Rate constraints for Input target for smoother response
Minor:
- added 2 beep sound when motors get enabled
- minor bugfixes
The follwing were converted to fixed-point
- battery voltage
- board temperature
- filters for steer and speed
- mixer calculation
Starting from this moment, the firmware is floating point free, meaning it runs more efficiently.
