State-space approach to single-phase PLL synthesis

State-space approach to single-phase PLL synthesis, that include modal controller and Luenberger observer.

*.m-file contains a program for calculating the coefficients of the modal controller and the Luenberger observer. You need to run the program to save the parameters to the workspace.
Simulink model consist of h-bridge controlled by pulse-width modulation. The voltage frequency is determined by two PLL systems: one is built into the MatLab, the other is offered.
