Abstract
A model-based control method includes: (a) acquiring temperature control data including temperature data of each of a plurality of zones of a temperature control member provided in a processing apparatus, temperature of each of the plurality of zones being individually controllable; (b) for each zone, specifying a temperature of another zone that is weight-averaged by a weighting coefficient determined according to a magnitude of heat transfer with the another zone; (c) for each zone, specifying a parameter of a state-space model of multi-input/single-output using the specified temperature of the another zone and the temperature control data; (d) creating a state-space model of multi-input/multi-output by assigning the specified parameter of the state-space model of multi-input/single-output to each element of the state-space model of multi-input/multi-output; and (e) controlling the temperature of each of the plurality of zones of the temperature control member using the state-space model of multi-input/multi-output.
