Abstract

Preferably in a flight control system has a bias correcting phase compensating rate limiter 302 to control movement of a device 306 such as an actuator. The bias correcting phase compensating rate limiter includes a switching arrangement 338 adapted to reverse a polarity of an error signal in response to a set of predetermined conditions 340 that include a commanded rate of movement 304of the device exceeding a rate limit capability of the device; a time rate of change Š U of an input signal to the rate limiter being opposite in polarity to a difference Š Y between the input signal to the rate limiter and an output signal from the rate limiter, which may be determined in a module 346; and a time rate of change of the input signal to the rate limiter being opposite in polarity to a difference Š X between the output signal Y' from the rate limiter and a signal corresponding to a pre-specified neutral or trim position UTRIM of the device.
