ABSTRACT:
A PID parameter adjustment device includes: a model storage section (1) for storing an equation model to be controlled; a PID controller storage section (2) for storing a control algorithm; a constraint condition storage section (3) for storing a constraint condition for the operation; a simulation operation section (5) for executing simulation of a control system according to the constraint condition; an ideal control result storage section (6) for storing an ideal control response characteristic; an evaluation function operation section (7) for calculating the evaluation function value indicating the closeness between the simulation result and the ideal control response characteristic; and a PID parameter search operation section (8) for executing simulation while modifying the PID parameter and searching a PID parameter at which the evaluation function value is optimal.
