Abstract
A hybrid control system for controlling an electric machine coupled to a gas turbine engine is provided. The control system comprises: a primary analog control loop including an analog controller for controlling the electric machine based on a set point and a measured output of the electric machine; and a digital controller of the turbine engine operationally connected to the primary analog control loop to adjust at least one control parameter associated with the analog controller.

A hybrid control system for controlling an electric machine coupled to a gas turbine engine, the control system comprising:
- a primary analog control loop including an analog controller for controlling the electric machine based on a set point and a measured output of the electric machine;
- and
- a digital controller of the turbine engine operationally connected to the primary analog control loop to adjust at least one control parameter associated with the analog controller.
A method for the analog control of an electric generator coupled to a gas turbine engine, the method comprising:
- controlling an output of the generator based on a set point, a measured output of the generator and at least one control parameter;
- and
- adjusting the at least one control parameter based on a digitally derived signal.
A control system for controlling an electric generator coupled to a gas turbine engine, the control system comprising:
- a primary analog means for controlling the machine based on a set point and a measured output of the generator;
- and
- a digital control means of the gas turbine engine connected to the primary analog means, the digital control means being configured to supervise the operation of the primary analog means.
