Claim 0:
1. A multi device coordination control device for controlling a plurality of actuator devices disposed in the same physical space, the multi device coordination control device comprising:
a degree-of-service-achievement calculator, including one or more processors, configured to acquire prescribed information on the physical space as sensor information from one or more sensor devices disposed on the same physical space, and convert a value indicated by the acquired sensor information, to a degree of service achievement, the degree of service achievement being an indicator showing to what degree a purpose of a prescribed service realized by controlling the actuator device is achieved;
a target control amount calculation part, including one or more processors, comprising a learning device in which machine learning is performed such that, upon an input of the degree of service achievement, an actuator control amount for each of the actuator devices, designed to satisfy a targeted degree of service achievement which is a target of a degree of service achievement for each service, is computed and outputted, the target control amount calculation part being configured to make the learning device allow an input of the degree of service achievement obtained by the conversion as an input value, and make the learning device compute therefrom an actuator control amount for each of the actuator devices, to thereby obtain the actuator control amount for each of the actuator devices as an output value; and
an actuator controller, including one or more processors, configured to convert the actuator control amount obtained as the output value to a control instruction in accordance with each of the actuator devices, and transmit the obtained control instruction to each of the actuator devices, to thereby make the each of the actuator devices execute the control instruction,
further comprising a control amount adjustment part configured to adjust an actuator control amount for each of the actuator devices,
wherein, after the actuator device executes the control instruction, the degree-of-service-achievement calculator is configured to again acquire sensor information from the one or more sensor devices, and calculate a degree of service achievement after the control of the actuator device is performed, based on a value obtained from the acquired sensor information;
wherein, if the degree of service achievement after the control is smaller than the targeted degree of service achievement, the control amount adjustment part is configured to calculate an adjustment control amount of the actuator device by applying evolution strategy algorithm using a degree of difference, the degree of difference being an indicator showing to what extent the degree of service achievement obtained this time after the control, is different from the targeted degree of service achievement, then calculate an actuator control amount after an adjustment of interest is made, using the calculated adjustment control amount and an actuator adjustment reference amount, the actuator adjustment reference amount being a reference for adjusting an actuator control amount of this time, and, if the degree of service achievement after the control is larger than the degree of service achievement just before the control, update the actuator adjustment reference amount with the actuator control amount of this time; and
wherein the actuator controller is configured to convert the actuator control amount after the adjustment, to a control instruction in accordance with each of the actuator devices, and transmits the control instruction thereto, to thereby make each of the actuator devices execute the control instruction.
