Abstract

A simulator system for use in providing an event simulation to occupants includes a motion base moveable along displacement axes by means of displaceable actuators. Feedback sensors provide signals indicative of the measured displacement of a corresponding actuator. An audio-visual display mechanism is included for providing a sequence of audio and visual images to the occupants. A motion base controller receives the feedback sensor signals and generates actuator drive signals below a cutoff frequency in response to received command signals. A system controller provides the command signals to the motion base controller in synchronization with the presentation of the audio-visual images to the occupants. A mechanism is included for generating supplemental actuator drive signals that have frequencies above the cutoff frequency. A drive signal summing apparatus serially configured with the motion base controller and the actuators receives the actuator drive signals and sums therewith the supplemental actuator drive signals before presentation to the actuators.
