Servo-control unit

Abstract

Abstract PURPOSE:To facilitate a speed control of a control object by making an array of a moving extent per unit time from a target moving extent and a target speed, adding an array of a moving extend '0' or a moving extent being equivalent thereto, and averaging the array in order. CONSTITUTION:Suppose that a moving command is inputted to a control part 10 to move a control object from the point A to B with the velocity of 50mm/sec. where the distance between the positions A and B, the projected distance of the line AB in the X axis direction, and the distance in the Y axis direction are 500mm, 400mm and 300mm, respectively. The control part 10 derives a moving extent >=X=50/500X400=40mm per unit time in the X axis direction (Y axis direction) from a given data and arrays it. Subsequently, a moving extent per unit time is obtained by adding an array of a moving extent '0' before and after the array, putting a code at every unit time, deriving an average value, while shifting the unit time one by one and executing the averaging. This moving extent becomes a speed command in the X axis (Y axis) direction. By adding successively these speed commands, a moving distance in the X axis (Y axis) direction from the position A is obtained. By comparing with the present position outputted from a position detector 9, a position command in the X axis (Y axis) direction is obtained and outputted to a subtracter 4.
