PID control method and PID controller for determining, from a control response from a process, characteristic values representative of controllability and automatically deriving and setting PID constants from the determined characteristic values. The error between a set point and a controlled value is decided as to whether to be due to a change in set point or due to a disturbance, and PID constants are set on the basis of results of decision.
