Blended mode concept for control of flight simulator motion systems

Image Number 3 for United States Patent #4576577.

The invention relates to a motion simulator system, for example, a flight simulator system. In accordance with the invention, the system is driven by command signals representing both position and acceleration, and a circuit is provided to process and combine the signals to provide a system command signal. High frequency position command signals, and low frequency acceleration command signals, are eliminated by their drive circuits, and all command signals are varying electrical voltages.
