Abstract
A human-operated system comprises a positioning system and an input shaper. The positioning system moves an object from one location to another. The positioning system includes a computing device that controls the movement of the positioning system responsive to receiving a user command. The input shaper is coupled to the computing device of the positioning system. The computing device estimates an overtravel of the positioning system and determines an overtravel constraint that is factored into the movement of the positioning device. The computing device moves the positioning system based on the overtravel constraint in a manner that limits the overtravel, deflection and vibration of the object as the object is moved from one location to another. The human-operated system includes a predictive element that represents a predictor location responsive to the user command provided by the human operator, which aids the human operator position the positioning system.
