- the PID control algorithm is used for the control of almost all loops in the process industries, and is also the basis for many advanced control algorithms and strategies. Standard methods for tuning loops and criteria for judging the loop tuning have been used for many years, but should be reevaluated for use on modern digital control systems. For the shortcomings of traditional PID control, a composite PID fuzzy control method for transformer cooling system is proposed. The method combines fuzzy control and PID control, which form composite fuzzy PID control method based on conventional PID control. With obtain temperature from the thermometer, it can find input error E and error change EC, and quantify the fuzzy, compute fuzzy control table, check the table to obtain fuzzy control parameter, find the actual PID input control parameter. Finally it find the output control parameter to the inverter. The proposed method uses PID proportional control to improve the dynamic response rate, and uses PID integral control to eliminate the steady state error, which improves the steady-state performance of fuzzy control, thus further improving energy savings transformer cooling system operation.
