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.
