Surge is due to the insufficient pressure, flow at suction. this causes the compressor to move to unstable region called surge.

Provide anti-surge controller which is of multi variable controller type to supply enough flow at the suction by recycling the discharge of compressor.

I faced several time siemens ps2 positioner automatically getting Chang in it's set point direction after auto calibration  So is there any causes biside this or  any  permissives ?
