Abstract
A PID parameter adjustment device includes: a model storage section () for storing an equation model to be controlled; a PID controller storage section () for storing a control algorithm; a constraint condition storage section () for storing a constraint condition for the operation; a simulation operation section () for executing simulation of a control system according to the constraint condition; an ideal control result storage section () for storing an ideal control response characteristic; an evaluation function operation section () 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 () for executing simulation while modifying the PID parameter and searching a PID parameter at which the evaluation function value is optimal.
