Summary

TO SUPPRESS COMPRESSOR VIBRATION DUE TO TORQUE EXCITATION, A TORQUE CONTROL SYSTEM IS APPLIED. THIS METHOD USES A MICROCOMPUTER, WHICH MAKES THE MOTOR OUTPUT TORQUE NEARLY EQUAL TO THE LOAD TORQUE VARIATION WHICH IS CAUSED BY GAS COMPRESSION AT ANY ANGULAR POSITION. THEORETICAL ANALYSIS AND COMPUTER SIMULATION SHOW THAT THE CONTROL SYSTEM, IN WHICH THE ROTATIONAL VARIATION IS CAUSED BY THE TORQUE DIFFERENCE, IS DETECTED DURING ONE REVOLUTION AND IS REFLECTED TO THE MOTOR OUTPUT TORQUE AT THE NEXT REVOLUTION, DUE TO THE CYCLIC CHARACTERISTIC OF THE LOAD TORQUE.
