Abstract
A servo control system has a motor for a control and a device for commanding target distance and velocity of movement of the control so as to actuate the motor in accordance with commands from the commanding device. The system further includes a distribution device for determining a set of distances of movement for a set of like number of unit times respectively on the basis of the target distance and velocity of movement; a device for adding predetermined numbers of unit times, in each of which the distance of movement is set at zero, before and after the set of the like number of the unit times, respectively; a device for setting a set of weights for the positions of movement for the like number of unit times, respectively; and an averaging device for successively adding the weights to the positions of movement for the like number of unit times, respectively, and averaging the resulting weighted position of movement of a first unit time and those of a desired number of preceding successive unit times to calculate a target position for the first unit time, and then repeating a similar averaging operation successively with respect to each of the remaining unit times in the order of sequence of the remaining unit times until a target position for a last time unit is calculated.
