Abstract
A control device configured to perform feedback control by transmitting a control signal to a target device based on a physical quantity of the target device measured by a sensor and a command value includes: a receiver configured to receive the physical quantity to which a transmission sequence number incremented for each control cycle is added in a sensor driver; a buffer unit configured to hold an array of a number of elements determined based on a maximum value of a number of delay periods; a control unit configured to generate the control signal based on the physical quantity and the command value; and a transmitter configured to transmit the control signal to the target device. The control unit increments a reception sequence number for each control cycle, stores the physical quantity at a storage position of an array determined based on the transmission sequence number and the reception sequence number, and generates the control signal based on the physical quantity stored in a storage position for control, and the command value.
