Summary:In previous study, H-infinity control theory was applied in order to establish high reliability of a torque converter lock-up clutch slip control system, so that it was confirmed that robust stalility against large characteristic variation of the plant was ensured. There is, however, a problem of requiring much time to perform the procedure from the modeling to the designing of the control system because of many experimental data under various conditions to obtain practicable models. We propose new design method that shortens the design time by representing the plant model by interpolation of vertex characteristics, which represent boundary of model set made from the data and knowledge accumulated in the past, and can construct the control system on an onboard ECU. In this paper we aim at modeling in the above method, and show that the time for modeling has been shortened greatly as compared with the conventional method.
