Title: How to take Phase from PLL output in Matlab Simulink
Post by Ata on Dec 11^th, 2013, 12:54am

We know known the PLL output is Sin(Φout) where Φout=ωout*t+Θ(t),for stability and calculation of the PLL loop I have to find transfer function of Φout(s)/ Φin(s). The Problem is how can I Take Φout from Sin( Φout) in Matlab simulink?

Iam looking for something like arcsin() function but as arcsin lies down in [-pi/2,pi/2] region therefore it is of no use :(

you model is in time-domain, or phase domain?

If u wanna check stability, loop BW, u need to do phase-domain model, s-domain.

If u need to check transient behaviour, u have to do time-domain model.
