Title:
FEEDFORWARD SIGNAL GENERATING METHOD OF SERVO SYSTEM
Document Type and Number:
Japanese Patent JPS58214905
Kind Code:
A
Abstract:
PURPOSE:To ensure the control with high responsiveness and high accuracy, by performing a prescribed operation synchronously with the time indicated from a set of constants that is commanded from a command generator for each dispersing time interval and then adding the result of operation to an answering signal. CONSTITUTION:A set of constants (e.g. position X, speed V and acceleration A) is supplied from a command generator for each dispersing time interval. The acceleration A is supplied to an acceleration loop controller Ga in the form of an addition input signal Ar as well as to an integrator 1. Then the sum of the output Vi of the integrator 1 and the speed V is fed to a speed loop controller Gv as an addition input signal Vr as well as to an integrator 2. The sum of the output Xi of the integrator 2 and the position X is fed to a position loop controller Gp as an addition input signal Xr. Then an acceleration X is transmitted via a motor and integrators 3 and 4 for transmission function Gm of driving circuit. At the same time, a reset signal RS is generated synchronously with the timing indicated from the command generator. Then integrators 1 and 2 are reset.
