Flight Simulation Motion-Base Drive Algorithms. Part 2. Selecting the System Parameters

摘要

A project aimed at developing and testing flight simulator motion-base drive algorithms suited for commercial jet transports is discussed. Full six degrees-of-freedom motion of a synergistic motion-base is being studied. Three forms for these algorithms are being considered: (1) classical linear washout, (2) optimal control, and (3) coordinated adaptive washout. It is felt that the latter two techniques may provide some advantages over the classical, which is currently employed in most commercial flight simulators. A filter parameter selection process using typical jet transport maneuvers as input signals is discussed. The filter parameters were adjusted to produce a range of washout characteristics. The pilot's motion sensations produced by these tests were estimated through the use of linear models of the human vestibular system. Nine sets of washout filters were generated for future evaluation by a group of pilots. Computer listings of the real-time software are presented along with numerous test results.
