Hi,
Is there anyone from Cypress that can tell me what the Low Pass Filter is that is used in the Speed Estimator calculation?
/* struct definition for speed estimator*/
typedef struct
{
q15_t curTheta; /* Current Electrical angle */
q15_t oldTheta; /* Old Electrical angle */
q15_t estimatedSpeed; /* Estimated speed in per-unit */
q15_t baseRpm; /* Base speed in rpm */
q15_t intervalConst; /* Constant for differentiator */
q15_t filterConst; /* Constant for low-pass filter */
q15_t estimatedSpeedRpm; /* Estimated speed in rpm */
} SpeedEstimator;
Thankyou.

When nobody answeres I would suggest you to create a support case to get in contact with Cypress directly. At top of this page select "Design Support -> Create a Support Case" and describe your problem.
