Abstract
A multi-rate system for controlling an actuator may include an incremental command limiter that receives a command from a first control system and outputs a limited incremental command; a feed-forward that receives the limited incremental command from the incremental command limiter and outputs a feed forward rate command; a first differentiator that limits the limited incremental command to a maximum allowable command; an upsampler state that outputs a current state back to the differentiator; a first summer that receives the limited incremental command and the current state from the upsampler state, and outputs an incremental position command; and a second summer that combines the incremental position command and the feed forward rate command to produce a rate error output signal.
