Abstract
A compound control method involves Proportional Plus Integral Plus Derivative Control (PID control) and Fuzzy Control. The method controls a system by inputting output data of the system to be controlled to a PID control operation so as to obtain a control variable from the PID control operation, inputting the output data also to a fuzzy operation so as to obtain a correcting variable from the fuzzy operation, correcting the control variable by the correcting variable so as to obtain a corrected control variable, and controlling the system by the corrected control variable.
