Abstract
A machine control system for controlling an unstable or transition running condition of a machine which is operable by a causative signal and the performance of which is indicatable by an indicative signal. The control system includes: (a) a model-based control unit for outputting an estimated value of a causative signal when receiving an indicative signal, which model-based control unit undergoes learning based on teacher data; (b) a feedback control unit for providing first teacher data to the model-control unit upon receiving feedback information from the machine; and (c) an anticipatory control unit for providing second teacher data to the model-based control unit. The anticipatory control unit includes: (i) a deviation detection program programmed to determine whether the running condition of the machine deviates from a predetermined stable running condition; and (ii) a compensation formulation program programmed to formulate anticipatory compensations to compensate for deviation of the machine from the predetermined stable running condition based on feedback information received from the machine, output from which program is provided to the model-based control unit as second teacher data.
