Example wireless feedback control systems disclosed herein include a receiver to receive a first measurement of a target system via a first wireless link. Disclosed example systems also include a neural network to predict a value of a state of the target system at a future time relative to a prior time associated with the first measurement, the neural network to predict the value of the state of the target system based on the first measurement and a prior sequence of values of a control signal previously generated to control the target system during a time interval between the prior time and the future time, and the neural network to output the predicted value of the state of the target system to a controller. Disclosed example systems further include a transmitter to transmit a new value of the control signal to the target system via a second wireless link.

A robot synchronization sealer discharge system is provided. The robot synchronization sealer discharge system is interlocked with a robot for a sealer work of a vehicle factory and includes: a sealer gun mounted on a robot and moving along an application path of a vehicle body to discharge a sealer and a communication unit for receiving a TCP speed of the sealer gun moving based on robot operation. A synchronization controller assigns a unique ID and a received TCP time to the TCP speed and generates a discharge instruction message recording the sealer discharge amount according to the TCP speed. A sealer controller adjusts a discharge of the sealer gun based on the discharge instruction message and feeds back the sealer time according to a discharge completion to the synchronization controller.

A control device controls a mechanical device having a movable member driven by a motor. The control device includes a radio signal exchange unit that receives a sensor signal indicating a position, a velocity or an acceleration of a tip part of the movable member, a data acquisition unit that acquires first time-series data of acceleration based on the received sensor signal, a data calculation unit that calculates second time-series data of acceleration at the tip part based on a drive command to the motor, a delay time calculation unit that calculates, when the mechanical device performs a predetermined basic operation, a delay time of the first time-series data to the second time-series data, based on a degree of correlation between the first and second time-series data, and a time synchronization unit that synchronizes time of the sensor part and control device based on the delay time.

A motion controller has an axis control part and a communication control part. The motion controller includes: a control function storage part that stores a control function received from a higher-level control device by the communication control part; a control function execution part that executes the control function regarding at least one of information of a motor and information of a sensor as an input; and a control information changing part that changes the motor control information based on a result of execution of the control function stored in the control function storage part, the execution of the control function being performed by the control function execution part. The motor control information changed by the control information changing part serves as an input to the axis control part.

A terminal communication apparatus has a terminal communication control portion rendering an immediate communication control portion sequentially transmitting serial data to another terminal communication apparatus bitwise when receiving a packet as bitwise serial data and a normal communication control portion performing processing on the packet after accumulating the serial data until the serial data reaches a packet length when receiving the bitwise serial data switchable, performing processing with the immediate communication control portion in a case of receiving a time adjustment packet containing time adjustment data posting a timing of synchronization in the other terminal communication apparatus and performing processing with the normal communication control portion in a case of receiving a packet other than the time adjustment packet. Thus, synchronization of control object devices can be enabled without previously investigating communication delay times.
