摘要： A load counterbalancing system with a constant load displacement force includes a load element, a position transducer and an actuator element. An environmental force acting upon the load element is counterbalanced by a support force provided by the actuator element. The environmental force is assumed to be a predetermined function of the position of the load element, and the actuator element applies the support force to the load element as defined by the predetermined function. The invention allows an operator to move the load element through its entire range of motion with a constant applied force, and to place the load element statically at any position in the range of motion.
