This paper is devoted to the design of a nonlinear controller well suited for the voltage regulation of embedded AC electrical networks, such as plane or ship power systems. The approach may also be applied without fundamental restriction to high voltage or distribution power networks. The hereproposed approach relies on the nonlinear differential-algebraic dynamics of an aggregated electrical network based on the oneaxis model. The design is based on a linearization technique of this nonlinear differential-algebraic system coupled to a state estimator which reconstructs the full state vector of the network from easily measurable variables (voltages at network nodes). Simulations on the aggregated network demonstrate the effectiveness of the approach. Application of this approach to large-scale electrical networks is also discussed.
