Patent JP-H03195383-A (JP)
Title: Motor controller
Inventor: YOKOZUKA MASARU
IPC: H02P29/00
Filed: 1989-12-22
Abstract: PURPOSE:To effect stabilized speed control without basing on the speed of a motor by a method wherein the speed of the motor is controlled at a reference speed based on a difference between a speed signal and the reference speed as well as a control gain. CONSTITUTION:When the speed of a motor 1 is slow, a pulse interval from an encoder 2 is elongated and the interval of output of control amount with respect to the motor 1 is also elongated. In this case, a control gain is set so as to be low and, therefore, the sudden speed change of the motor may be restrained. On the other hand, when the speed of the motor 1 is increased and the pulse interval from the encoder 2 is shortened, the output interval of the control amount with respect to the motor 1 is shortened and, therefore, the control gain is set so as to be higher in accordance with it. The control of the speed of a motor to a reference speed, having good response, may be effected in such a manner.

Inventor: EDA TATSUO
IPC: H02P25/06
Filed: 1990-11-29
Abstract: PURPOSE:To run a movable piece smoothly by a method wherein driving current is commutated through open loop control and commutating timing is switched so that the movable piece receives a driving force intermittently while including division in which the movable piece runs by inertia. CONSTITUTION:A movable piece is provided with driving force intermittently. Said driving force includes accelerating force and decelerating force. During a driving division, in which the movable piece receives the driving force, the movable piece is accelerated or decelerated. In a division, in which the driving force is not applied, it becomes an inertia running division, in which the movable piece runs by the inertia thereof. The movable piece, whose acceleration or deceleration is dulled in the inertia division, is accelerated or decelerated again in the next driving division and the running of the movable piece is continued by repeating the acceleration and deceleration. According to this method, when a gap is generated between commutating timing and the motion of the movable piece due to the fluctuation of a load, the gap is absorbed in every inertia runnings of the movable piece and will never be increased through synergistic effect. On the other hand, the acceleration of a running body is restrained in the inertia running division of the same.
