Hi Expert,

I have s question about our SFRA library:

static inline float32_t DCL_runDF22_C4(DCL_DF22 *p, float32_t ek)

ek (servo error) does it mean the error of control command minus feedback?

Does this function meaning the same 2P2Z as following?

BR,

Seamus,

This is not from SFRA but related to DCL Library. So, looping in Sen for the response.

Thanks,

Shashank

Hi Seamus,

I'm terribly sorry for the delay.

Yes the servo error "e(k)" is the difference between the control reference "r(k)" minus the measured feedback value "y(k)".

And arthmetic wise DF22 is analogous to the general two-pole two-zero compensator design, which is applicable to the 2P2Z under the compensator designer as well.

Please let me know if I can further assist you.

Best,

Sen Wang
