50Hz proportional resonant controller (AC signal tracking)

A simple discrete 50Hz proportional resonant controller. Demonstration of 50Hz AC voltage single phase supply control

Proportional controller offers simplicity in tracking AC reference.

This model is a simple demonstration of a PR controller (proportional gain and resonant gain in parallel) which controls a voltage source to guarantee a 100V 50Hz voltage supply on the load.

The parameter is self-explanatory:

Tsc is the discrete controller sample time and

Ts is the system simulation time (used in unit delay to prevent algebraic loop)
