1. A turbine engine, comprising:
a compressor configured to pressurize an incoming air stream into a pressurized air stream;
a shaft system;
an electric generator operatively coupled with the compressor via the shaft system;
a power bus system comprising one or more controllable sources on the power bus system, the one or more controllable sources comprising at least one of a control element, a switch, or power electronics; and
one or more electrical loads electrically connectable with the electric generator through the power bus system; and
a controller configured to:
receive control data indicative of a system state of the compressor, the control data comprising at least one of a mass flow of the pressurized air stream through the compressor, a pressure of the pressurized air stream flowing through the compressor, and a rotational speed of the compressor;
determine a damping control command representative of instructions for adjusting the one or more electrical loads based at least in part on the control data; and
operate the power bus system to adjust an electrical load of the one or more electrical loads based at least in part on the damping control command so as to change the electrical load on the electric generator so that an output of the shaft system is changed for damping instability fluctuations of the pressurized air stream within the compressor.
