PID Parameter
/** UI_0104 PID Parameter */
float32_t
Motor_f32LowSpdKi =
float32_t
Motor_f32LowSpdKp =
float32_t
Motor_f32Dki
float32_t
Motor_f32Dkp
float32_t
Motor_f32Qki
float32_t
Motor_f32Qkp
float32_t
Motor_f32Skp
float32_t
Motor_f32Ski
uint16_t
Motor_u16ChgPiSpdHz = 10;
The PID parameter would be changed when the motor is not running stable at someone speed.
Filter Parameter
/** UI_0105 Filter */
float32_t Motor_f32BemfLpfkMinSpd
float32_t Motor_f32BemfLpfkMaxSpd
int32_t
Motor_i32Q12_BemfLpfkMin
int32_t
Motor_i32Q12_BemfLpfkMax
These parameters are used for the sensor-less rotor observer that is PLL estimator.
Hall Motor Start-up Parameter
/** UI_0106 Start-up param for hall motor*/
int32_t
Motor_StartSpd
float
Startup_InitCur
float
Startup_IncCur
float
Startup_SwitchCur = 0.3; //Switch current at closeloop
If the sensor motor does not start well, these parameter can be modified to make the motor start smooth.
