PURPOSE:To obtain a servo controller which can control the position by digitally processing a value of a deviation counter and a value from a pulse interval measuring counter. CONSTITUTION:A position deviation counter 1 counts a pulse from an encoder 6 which outputs a pulse train input from left side and a pulse proportional to the rotating amount of a DC motor 5, and outputs a position deviation. An amplifier 2 multiplies the deviation output of the counter 1 by multiplying by the constant time and outputs it to an adder 7. A speed counter 3 detects the angle speed of a motor by the output of the encoder, and outputs the constant multiplied value to the adder 7. A pulse width modulator 4 multiplies the output of the adder 7 by the pulse width in response to the output of the adder. Thus, the position can be controlled in response to the pulse input by the number of the input pulses, and the pulse input is set to an equal interval to control the speed. |
