Class CompressorAgent

java.lang.Object
neqsim.process.ml.multiagent.ProcessAgent
neqsim.process.ml.multiagent.CompressorAgent
All Implemented Interfaces:
Serializable, Agent
public class CompressorAgent extends ProcessAgent
RL agent for compressor control with anti-surge protection.

Controls:

  • Compressor speed for pressure/flow control
  • Recycle valve for anti-surge protection

Observations:

  • inlet_pressure - Suction pressure [bar]
  • outlet_pressure - Discharge pressure [bar]
  • compression_ratio - P_out/P_in
  • surge_fraction - Distance from surge line
  • speed - Current speed [normalized]
  • power - Shaft power [normalized]
  • pressure_error - Deviation from setpoint
