Abstract

In this paper, a novel approach to variable frequency optimal controller design for the application of aircraft embedded grids is presented. Aircraft power grids by industrial standards need to be able to operate across a range of frequencies. Often, these systems are controlled by active power-based controls, which are well known for being rather slow in response time. A novel method of variable frequency optimal control using H2 optimization is presented. It is shown that designing the control as such not only guarantees the optimal performance across the full range of frequencies being designed for, but fast responses to frequency and step load changes can be achieved.
