Zusammenfassung:	The present disclosure relates to a proportional, integral, derivative (PID) control system for controlling a cooling component of a cooling unit. The system may make use of a PID actuator position controller, a memory in communication with the PID actuator position controller, and a plurality of look-up tables. The look-up tables may be stored in the memory and may set forth different proportional "P", integral ("I") and derivative ("D") gains based on an operating variable associated with operation of the cooling component of the cooling unit. The PID actuator position controller uses the lookup tables together with determination of projected data and historical data, to adjust at least one of the P, I and D gains in real time.
