Claim Text:
1. A system configured to provide a regulated generator field current to a generator to acquire a regulated output voltage of the generator, the system comprising: a controller configured to provide an actuator control signal on the basis of an error signal; an actuator configured to provide on the basis of the actuator control signal a pulse-width modulated output voltage that is configured to drive the regulated generator field current into the generator, the pulse-width modulated output signal having a duty cycle controlled by the actuator control signal; and an error evaluator configured to provide the error signal based on a combination of a first deviation signal and a second deviation signal, wherein the first deviation signal represents a difference between a voltage setpoint value and a generator output voltage and the second deviation signal represents a difference between a duty cycle limit value and a signal representing the low-pass filtered actuator control signal.
