Nonlinear control
Abstract
Abstract A CONTROL FOR INDUCING MOVEMENT TO A MOTION TRANSMITTING DEVICE AS A NONLINEAR FUNCTION OF THE MOVEMENT APPLIED TO THE CONTROL LEVER. THE WORKING ELEMENT OF A MECHANICAL MOTION TRANSMITTING DEVICE IS SECURED TO A CONNECTOR THAT IS ROTATABLY CARRIED ON A THROW MEMBER. THE THROW MEMBER IS, IN TURN, MOUNTED ON A FRAME FOR SWINGING MOVEMENT ABOUT SELECTIVE PIVOT AXES LOCATED ECCENTRICALLY OF THE AXIS ABOUT WHICH THE CONNECTOR IS ROTATABLY CARRIED ON THE THROW MEMBER. THESE AXES ARE PARALLEL AND LIE WITHIN THE SAME REFERENCE PLANE WHEN THE CONTROL LEVER, SECURED TO THE THROW MEMBER, IS IN ITS NEUTRAL POSITION. FROM THIS NEUTRAL POSITION THE CONTROL LEVER IS MOVABLE THROUGH FIRST AND SECOND OPERATING RANGES, AND INTERLOCK MEANS RESTRICT THE THROW MEMBER TO MOVEMENT ABOUT THE AXIS OF ONE PIVOT MEANS WHEN THE CONTROL LEVER IS WITHIN THE FIRST OIPERATING RANGE, AND, SIMILARLY, TO MOVEMENT ABOUT THE AXIS OF THE OTHER PIVOT MEANS WHEN THE CONTROL LEVER IS WITHIN THE SECOND OPERATING RANGE. MOVEMENT OF THE THROW MEMBER ABOUT THESE SELECTIVE AXES, DISPLACED FROM THE AXIS ABOUT WHICH THE WORKING ELEMENT OF THE MOTION TRANSMITTING DEVICE IS CONNECTED TO THE THROW MEMBER, EFFECTS TRANSMISSION OF MOTION BY THE MOTION TRANSMITTING DEVICE THAT IS A NONLINEAR FUNCTION OF THE MOVEMENT APPLIED TO THE CONTROL LEVER.
