TMDSSOLARUINVKIT: CNTL_2P2Z_CoefStruct Parameter explanation.

Hi all,

In solar library CNTL_2P2Z_(IQ/F/CLA).h file contain the 2-pole 2-zero control block which implements a second order control aw using an IIR filter structure with programmable output saturation.

1. How to calculate satmax, satmin, i_satmin?

Thanks

    satmax, satmin and i_satmin are typically not mathematically computed. Depending on the topology and modulation used you will know if you want to put any limits on the duty cycle you want to put and that would determine your limits.

    isatmin is only used to prevent long interval of integral windup by limiting what values specially usefull in PFC aplication when working under no load.

    You can keep isatmin same as satmin or keep it slightly negative to help with above.
