A problem about the algorithm of S-type acceleration and deceleration

maxxu — Sat, 29 May 2021 09:17:33 GMT

Hello everyone, I am currently designing a BLDC driver based on position control。

I use function the libraries ，MC9S12ZVM_AMMCLIB_RTM_1_1_23_BIN.

Is there a function or reference design for T-type acceleration / deceleration or S-type acceleration / deceleration

Thank you very much

Hello,

There is no such a function in the library yet, however, you can create one using basic blocks (e.g. two integrators in series with look-up tables of input jerk / acceleration limit, or, square root function directly).

Best regards,
