Title: Position control system
Inventor: INOUE KENJI
IPC: G05D3/12
Filed: 1991-03-22
Abstract: PURPOSE:To improve a follow-up property to a command at the time of acceleration/deceleration by finding out a positional deviation of a command pulse and a feedback pulse, integrating the deviation and applying the integrated result to a position command input stage. CONSTITUTION:Ths position control system has a speed minor loop and a feedforward pass for detecting the frequency of a pulse command and supplying the detected frequency to the speed minor loop to execute positional control based upon the pulse command. A positional deviation compensating loop consisting of an adder 10 and an integrator 11 is connected to the front and rear terminal of the positional command input stage. Namely, the positional deviation compensating loop finds out a positional deviation between a pulse command and a feedback pulse by the adder 10, the deviation result is integrated by the integrator 11 and the integrated result is supplied to an adder 1. Thereby the positional deviation to be applied to the position control system in an acceleration/deceleration period becomes zero and the follow-up property to the command can be improved.

Abstract: PURPOSE:To interrupt penetration and introduction of a defect from a diffraction grating to an active layer by a superlattice layer, and to lengthen the life of a semiconductor laser by using the superlattice layer as an optical waveguide layer on the diffraction grating. CONSTITUTION:A waveguide layer on a diffraction grating 2 is shaped by a superlattice layer 7 consisting of thin-film multilayers, and a defect introduced from the diffraction grating 2 is stopped there by the superlattice layer 7, and is not admitted up to an active layer 8, thus improving the crystallizability of the active layer.
