Narrative:
While at cruise at FL360 we began to experience what felt like someone applying short; brisk; rudder inputs. These varied between left and right input; and there was no discernible pattern. The ride was smooth so as not to confuse this with any turbulence--supported by the flight attendants (flight attendant) who all remarked they noticed the unusual behavior. After we realized it was a continuing anomaly; and because there were no indications of any rudder input by lower EICAS or actual rudder pedals; we [notified] ATC. We initiated the descent; referenced the QRH to our situation as practical; and continued to [destination]. The anomaly lessened considerably below FL200; and the flight terminated without further incident. Upon arrival at the gate we were informed there was at least one historical event on this airplane related to rudder control.

Narrative: While at cruise at FL360 we began to experience what felt like someone applying short; brisk; rudder inputs. These varied between left and right input; and there was no discernible pattern. The ride was smooth so as not to confuse this with any turbulence--supported by the Flight Attendants (FA) who all remarked they noticed the unusual behavior. After we realized it was a continuing anomaly; and because there were no indications of any rudder input by lower EICAS or actual rudder pedals; we [notified] ATC. We initiated the descent; referenced the QRH to our situation as practical; and continued to [destination].
