Abstract

This paper describes work towards a non-linear multivariable controller for a flight simulator motion system. Significant performance improvements are expected over current industrial practice as a consequence of the following controller features: a compensation technique using non-linear pressure feedback to linearise the response of the electrohydraulic actuators; compensation for the main non-linear loading interactions between the actuators; acceleration control combined with position and velocity limits in such a way as to reduce noise sensitivity and improve robustness
