Tuning Active Power Factor Correction converter works in Simulink, but having trouble achieving the same in DPS

Here's what I would try, these strategies are not mutually exclusive Try to run your real system in open-loop. Given that your system is a power-factor corrector, you could probably simulate or ...

Multirate Control System Transfer Functions

The primary impact of a CIC filter in a control loop is the delay it introduces, as a linear phase filter, in addition the change in amplitude within the loop bandwidth. The gain reduction actually ...

Why is it necessary to have two state variables

It's useful to think in the definition of a Markov state: all information about the state at $t+1$ can be derived from state at time $t$ and control at time $t$, ONLY. No information older than $t$ ...

Different PI controller implementations and their respective discrete transfer functions

On the 2nd approach, your transfer function looks fine but translating it into C code appears wrong. To re-write your z-domain as a discrete finite difference equation where $y$ is the output and $a=...
