Claim 10:
11. A processing system, comprising:
a processing apparatus configured to process a substrate; and
a control system configured to control the processing apparatus,
wherein the control system includes:
a specifying part configured to, based on a recipe that describes conditions for processing the substrate, specify a model corresponding to the processing apparatus that processes the substrate and a control algorithm that generates a control signal for controlling the processing apparatus based on a measurement value measured by a measurement device provided in the processing apparatus so that a state of the processing apparatus becomes a predetermined state;
a simulator configured to simulate the state of the processing apparatus by using the model;
a first control signal generation part configured to generate a control signal based on the measurement value by using the control algorithm specified by the specifying part and configured to input the control signal generated by the first control signal generation part to the processing apparatus;
a characteristic amount generation part configured to generate a characteristic amount, which represents characteristics of the measurement value measured every first cycle, in each second cycle that is longer than the first cycle;
a second control signal generation part configured to generate a control signal based on an output value of the simulator, which corresponds to the measurement value, by using the control algorithm specified by the specifying part, and configured to input the control signal generated by the second control signal generation part to the simulator;
a first adjustment part configured to adjust a value of a model parameter included in the model so that a difference between the measurement value corresponding to the characteristic amount and the output value of the simulator is reduced; and
a second adjustment part configured to adjust a value of a control parameter included in the control algorithm used by the second control signal generation part so that an evaluation value calculated for the output value of the simulator using the model including the adjusted value of the model parameter becomes closer to a target value,
wherein the first control signal generation part is configured to generate the control signal by using the value of the control parameter adjusted by the second adjustment part, and
wherein the specifying part, the simulator, the second control signal generation part, the first adjustment part, and the second adjustment part constitute a first apparatus, and the first control signal generation part and the characteristic amount generation part constitute a second apparatus.
