Abstract

A process for controlling a gimballed motion base system substantially duplicating operator perceptions in a simulated vehicle. Such vehicles may include but not be limited to, aircraft, automobiles, boats, roller coasters, bob sleds, and futuristic space vehicles. The process includes: a subprocess accounting for an effect of yaw on a motion base arm, a full-G bias function and a limited-G bias function, a low-G bias function, improved computation of pitch and roll gimbal commands to negate artifacts, a negative-G process, allowing various yaw gimbal positions, allowing various cockpit orientations, and a yaw gimbal control process. A perceptual model based on empirically observed human response data predicts perceived pitch, roll, and yaw, and accounts for the fact that a Gy component of linear acceleration affects both roll and yaw perception.
