AUTOMATIC PERFORMANCE CONTROL OF COMPRESSOR BY MICROCOMPUTER.

Author(s) : LI L. X., YUAN H. P., SHU P. C.

Summary

THE PURPOSE OF THE PAPER IS TO MAKE A STUDY ON CAPACITY CONTRO L OF COMPRESSOR BY MEANS OF CHANGING THE RUNNING SPEED OF DRIVING MOTOR WHICH IS CONTROLLED BY A MICROCOMPUTER. THE AIM TO DEVELOP THIS CONTROL SYSTEM IS TO KEEP THE PRESSURE OF GAS TANK TO A DESIRED, APPROXIMATELY CONSTANT VALUE, IE THE PRESSURE DEVIATION IN THE TANK IS LIMITED TO A NARROW RANGE OVER THE DESIRED VALUE. THE CLOSED-LOOP CONTROL SYSTEM OF COMPRESSOR DRIVEN BY A SPEED-VARIABLE MOTOR IS DESIGNED, THE MATHEMATICAL MODEL AND CONTROL PROGRAM ARE DERIVED. THE PAPER COMPARES THE CONTROL SYSTEM WITH CLASSICAL INTERMITTENT SWITCHING THE DRIVING MOTOR ON OR OFF, AND PRESENTS THEIR POWER CONSUMPTION AND PERFORMANCE CHARACTERISTICS.
