Publication number: 20210365033Abstract: An operation path generation unit (210) generates an operation quantity time series for an actuator (111) based on a measurement state quantity output from a state sensor (101). A predictive model unit (220) generates a state quantity predictive time series by calculating a predictive model by using as an input the measurement state quantity and the operation quantity time series. A neural network unit (230) corrects the state quantity predictive time series by performing arithmetic operation of a neural network, by using as an input a measurement environment quantity output from an environment sensor (102) and the state quantity predictive time series. A state quantity evaluation unit (240) generates an evaluation result for the state quantity time series after the correction. The operation path generation unit outputs an operation quantity at the head of the operation quantity time series to the actuator when the evaluation result fulfils an appropriate criterion.Type: ApplicationFiled: August 3, 2021Publication date: November 25, 2021Applicant: Mitsubishi Electric CorporationInventors: Hidekazu SEGAWA, Atsushi SETTSU, Masakatsu TOYAMA, Hiroki KONAKA
