Title: Rotation restraint device
Inventor: KUBO TADAYUKI
IPC: G03F9/00
Filed: 1990-07-19
Abstract: PURPOSE:To eliminate resistance of friction, etc., to prevent a table from slanting when driven, and to enable highly accurate feeding by restraining the degree of freedom of the direction of rotation to a base plate by a static pressure bearing. CONSTITUTION:When pressurized air is supplied to air feed hoses 15 and 15' and valves 16 and 16' are opened, the pressurized air is supplied to porous bodies 8 and 8' through air feed holes 9 and 9'. Consequently, liquid lubricating films are formed in fine gaps 13 and 13' and the porous bodies 8 and 8' support both sides of a guide member 5 in opposite directions without contacting. Consequently, the motion of the table 1 in the rotating direction is restrained. In this state, the table 1 is moved to the base plate 2 in the normal direction and when one valve 16 is closed at an optional position to stop supplying the pressurized air to the air feed hole 9, the guide 5 is pressed against the porous body 8 with the pressure of the liquid lubricating film formed in the fine gap 3' on the opposite side to fix and hold the table 1. Therefore, the table is fed with high accuracy and held with high rigidity in the moving direction at the stop.

Title: Learning method for feedforward gain under control of motor
Inventor: NIHEI AKIRA
IPC: G05B13/02
Filed: 1990-07-18
Abstract: PURPOSE:To set the optimum feedforward gain even when the inertia of a control system is unknown and to heighten follow-up ability for a command by finding a feedforward gain by learning. CONSTITUTION:This method is comprised of a host CPU 1, a digital servo circuit 3, a feedback signal register 4, and a robot 5. The feedforward gain K is decided by the learning based on equation I by setting relation X=(1+KS) U assuming the feedforward gain as K, a time as (t), deviation quantity as VER, command value as U, and a positive constant near to zero as (alpha). In such a way, it is possible to converge the deviation quantity to a minimum value zero by deciding the feedforward gain based on equation I. Thereby, the optimum feedforward gain can be decided by the learning, and the method can be applied to the control system in which load inertia is remarkably fluctuated.
