ABSTRACT:
A bias correcting phase compensating rate limiter to control movement of a device may include a switching arrangement adapted to reverse a polarity of an error signal in response to a set of predetermined conditions that may include a commanded rate of movement of the device exceeding a rate limit capability of the device; a time rate of change of an input signal to the rate limiter being opposite in polarity to a difference between the input signal to the rate limiter and an output signal from the rate limiter; and a time rate of change of the input signal to the rate limiter being opposite in polarity to a difference between the output signal from the rate limiter and a signal corresponding to a pre-specified neutral or trim position of the device.
