Q: Algebraic Loop Error (Simulink)

Hi,

I am building a Maximum Power Point Tracker (MPPT) configuration for solar array on simulink and i am facing an algebraic loop error. I've tried using a unit delay to rectify this problem but it came to no avail as i might have done it wrongly. As attached is the error message.

Also, my MPPT configuration is as attached.

Your help is greatly appreciated! Thanks!

Best Regards, SY
