### 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 $t$ ...

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=...
