Hi.
I'm trying to fly quad with RPM controller.
Below is my setting parameters.
#define DEFAULT_PWM_MIN_VALUE 990 // minimum to consider pulse a valid signal
#define DEFAULT_PWM_LO_VALUE 1020 // lowest running value
#define DEFAULT_PWM_HI_VALUE 2000 // highest running value
#define DEFAULT_PWM_MAX_VALUE 2020 // maximum to consider pulse a valid signal
#define DEFAULT_PWM_MIN_START 1045 // minimum value required to start
#define DEFAULT_PWM_RPM_SCALE 6500 // RPM equivalent of maximum PWM IN in CLOSED_LOOP mode
I think these parameters is not proper. Because, it is very hard to control BLDC motor with several hundred RPM.
If I have lower throttle, like 1070, then calculation will be
(1070 - 1020)/(2000-1020) * 6500 = 331.6327.
So the quad's propeller sounds like fluctuating.
Does anyone flew quad with RPM controller? If so, could you please let me know your settings?
