Claim 9:
10. A non-transitory computer-readable recording medium storing a control program that causes a control system to execute a process of:
based on a recipe that describes conditions for processing a substrate, specifying, by a specifying part, a model corresponding to a 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;
generating, by a first control signal generation part, a control signal based on the measurement value by using the specified control algorithm and inputting the generated control signal based on the measurement value to the processing apparatus;
generating, by a characteristic amount generation part, 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;
generating, by a second control signal generation part, a control signal based on an output value corresponding to the measurement value, as an output value of a simulator that simulates the state of the processing apparatus, by using the specified control algorithm, and inputting the generated control signal based on the output value to the simulator;
adjusting, by a first adjustment part, 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
adjusting, by a second adjustment part, a value of a control parameter included in the control algorithm 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 in the act of inputting the generated control signal to the processing apparatus, the control signal based on the measurement value is generated by using the adjusted value of the control parameter, 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.
