Title: Servo positioning control device
Inventor: SHINOHARA TORU
IPC: G05D3/12
Filed: 1987-12-08
Abstract: PURPOSE:To improve positioning tracing accuracy by controlling a driving part so as to be switched to an A-grade action after the operation of a B-grade action with a servo control part when a servo motor is servo-controlled to an aimed value. CONSTITUTION:A servo control part CT controls a driving part 6' so as to be switched to the A-grade action after an operation by the B-grade action. In a servo control process, the part 6' is switched to the B-grade action at a time point necessary for a large power, and to the A-grade action when the small power is sufficient. The A-grade action is not fit for the large power as well known, whereas, it does not generate crossover deviation, and promptly responds to the minute current displacement. On the other hand, for the positioning control, it initially drives the servo motor at high speed by a maxi mum current, and minutely controls the motor near the aimed position by the small current. Consequently, by driving the part 6' by the B-grade action, and then switching to the A-grade action near the aimed position, both the high- speed driving and high position tracing accuracy can be obtained.
