DEAD TIME REDUCING METHOD FOR SERVO CONTROL

摘要

PURPOSE: To provide a dead time reducing method for servo control which can reduce the dead time that is caused by the calculation needed for the proportion/integration control. ;CONSTITUTION: The proportion and integration calculations are carried out based on the control information on a servo system that is acquired at the rise of an FG pulse serving as a reference signal. Then the feedback control applying the proporion/integration control is attained by the software of a microcomputer. In such a control method, an output torque is decided based on the results of the precedent integration calculation and the proportion calculation of this time. Furthermore this decision processing is repeated every second time so that the dead time can be reduced for the servo control.;COPYRIGHT: (C)1995,JPO
