Abstract:
A personal simulator system having a display device for displaying simulated scenery depicting motion; said system comprising:A motion control device for indicating a desired change in the position of said system; A support plate; A pedestal support rigidly connected to said support plate at one end and having a coupling joint at the other end; A motion plate for supporting a rider, said motion plate coupled to said coupling joint; A plurality of AC fractional horsepower motors fixedly mounted on said support plate: A plurality of drive arm linkages, each coupled at one end to a respective one of said plurality of AC fractional horsepower motors and, at the other end, to said support plate; and A controller for generating a motor control signal to cause each of said plurality of AC fractional horsepower motors to cooperatively either reposition said motion plate by changing the relative orientation of at least one of said drive arms with respect to at least one other drive arm or for generating a dynamic boost motor control signal to maintain the current position of said at least one drive arm, said controller responsive to a positional control signal generated by said motion control device and having means for increasing motor torque at zero speed.
