要約(日本語): This paper describes tuning PID controllers using optimization subject to constraints on derivatives of control input, considering model uncertainty caused by changes in plant dynamics. Graphs by which the optimal PID parameters can be obtained are presented as functions of a normalized deadtime and a perturbation of plant parameters. To evaluate the control performance, the disturbance suppression and the reference tracking properties are presented compared to those by the partial model matching method and the H compensator designed for the same plant. Moreover, to avoid making the control system sensitive to measurement noise, the PI controller with a relaxation filter is newly developed. It is found that there is very little difference in control performance between the PI controller and the H compensator.
