    摘要: A fixed-position stop control apparatus (10) includes: a move-instruction generating means (22) for generating a move instruction for each control cycle; a position loop control means (25) for position controlling a rotation shaft (61) for each control cycle according to the move instruction generated by the move-instruction generating means; and a speed loop control means (35) for speed controlling the rotation shaft according to one of a speed instruction generated by a higher level control apparatus (45) and a predetermined speed instruction, thereby switching the speed control of the rotation shaft by the speed loop control means to the position control of the rotation shaft by the position loop control means. In this fixed-position stop control apparatus, the move instruction generated by the move-instruction generating means has acceleration smaller than the acceleration corresponding to the acceleration and deceleration ability of the rotation shaft. With this arrangement, time required for the rotation shaft to stop at a fixed position can be decreased.

    摘要: A digital servo system for causing a mechanical element (48) to track a desired path and hold various positions along the path and employing a lead/lag integrator (18) in parallel with a feedback control loop. The input to the integrator (18) is switched between velocity (V.sub.EK) error during pathtracking and position error (E.sub.K) during holding to increase the resistance of the mechanical element (48) to position changes caused by outside forces during both pathtracking and holding. The integrator function employed uses a term (U.sub.integrator(k-1)) representing a previous integrator output value to assist in smoothing perturbations caused by switching between position and velocity error.

    摘要: An electrohydraulic servo control system which includes a position feedback loop responsive to actual position at the hydraulic actuator and load, and a position command reference generator responsive to an operator joystick input command and to an operator mode select switch for generating a position command reference signal to the position loop as differing functions of the joystick input in each of the switch-selectable modes. The selectable modes of operation include an absolute position control mode wherein the joystick input is treated as indicating absolute desired position at the actuator and load, an incremental position control mode wherein the joystick input is treated as indicating desired change in position with reference to a base position, and a velocity control mode wherein the joystick input is treated as indicating velocity at the actuator and load desired by the operator.
