Abstract

Synchronous co-ordinate based Linear Quadratic Gaussian (LQG) phase voltage control is implemented. The regulation performance of the conventional LQG scheme is improved by using gain scheduling control that is based on the load current measurement. It is shown that the typical LQG scheme´s performance can be improved remarkably by not only introducing the load adaptive feedback but also replacing the integrator, that quarantees the zero steady-state error by proportional integration (PI) type of controller.
