A method and a device for carrying out a method for conducting vibration-diagnostic monitoring and assessment of individual machine parts (M1, . . . Mn) of a machine (M), preferably a rotating machine, using a frequency analyzer.

Methods and devices for diagnosing a robot. The method includes obtaining a first signal generated by a rotating component of the robot during operation of the robot. The first signal includes motion information of the rotating component. The first signal is preprocessed to filter out a part of the motion information in the first signal. The preprocessed first signal or spectrum information about the preprocessed first signal is sent to a server for diagnosing the robotU. A second signal is received from the server, wherein the second signal includes diagnostic information indicating whether a sub-component of the rotating component has a failure.

A control device includes: a processor wherein the processor is configured to generate one or more second control signals obtained by reducing at least one frequency component from a first control signal, output one control signal among the first control signal and the one or more second control signals, receive an instruction indicating execution of a reduction in the frequency component, generate a driving signal for driving a robot based on the control signal output from the processor and output the driving signal, output the first control signal when a first condition including non-input of the instruction indicating the execution of the reduction in the frequency component is satisfied, and output the second control signal when a second condition including input of the instruction indicating the execution of the reduction in the frequency component is satisfied.

A robot control device includes: a processor that is configured to execute computer-executable instructions so as to control a robot, wherein the processor is configured to: receive a first instruction from an operation device; display information regarding a target vibration frequency of a robot obtained based on vibration data indicating vibration of the robot in a certain time section on a display, when the processor receives the first instruction; set the target vibration frequency; generate a second control signal obtained by reducing the target vibration frequency from a first control signal based on the set target vibration frequency; and generate a driving signal to drive the robot based on the second control signal and output the driving signal.

A control device includes: a processor that is configured to execute computer-executable instructions so as to control a robot, and the processor is configured to receive an instruction to execute a specific operation which is an operation determined in advance; and an amplifier that causes a motor of a robot to execute the specific operation when the processor receives the instruction to execute the specific operation; wherein the processor is configured to receive a measurement result of vibration measured by a measurement device installed in the robot from the measurement device in the execution of the specific operation.

A sorting facility for items to be sorted, such as postal items, parcels, packages, baggage, suitcases, etc., includes carrying elements, conveyor paths at which the carrying elements are transported to target positions, to empty the items from a carrying element into a target position, a facility controller controlling movement of the carrying elements along the conveyor paths and emptying at the target positions, and a decentralized functional unit receiving process information regarding the conveyor paths and/or the carrying elements and, by comparison with nominal process information, detecting deviation from the nominal process information and reporting it to the controller. The functional units, which monitor the facility or surroundings, have computer-aided intelligence detecting and reporting deviations to the controller. Faults and/or impending faults, which can only be detected with difficulty or not at all, even in sorting facilities, are detected reliably and be reported timely to the controller.

Methods and apparatus to use vibration data to determine a condition of a process control device are disclosed. An example apparatus includes a vibration monitoring circuit to: collect first vibration data associated with a process control device during calibration of the process control device; calculate an operating threshold of the process control device based on the first vibration data; collect usage information associated with the process control device, the usage information indicative of a remaining portion of useful life associated with the process control device; adjust the operating threshold based on the usage information, the adjusted operating threshold reflective of the remaining portion of useful life associated with the process control device; and determine a condition of the process control device if second vibration data associated with the process control device collected after the calibration exceeds the adjusted operating threshold.

A decentralized control of decoupled plants which each include a motor and a load. A controller is connected in series with each decoupled plant. An adder is configured to receive a set point signal and a negative feedback signal from the plant output and generate an error signal. Each controller receives a set of tuning parameters, modifies the error signal based on a tuning parameter space vector and generates drive signals which actuate the motor, operate the load, and generate the plant output in accordance with a frequency domain assessment function. A compensator samples the error signals and the plant outputs, Fourier transforms the error signals, generates the tuning parameter space vector, based on a frequency domain assessment function, obtains the set of tuning parameters from the tuning parameter space vector, and transmits the frequency domain assessment function and the set of tuning parameters to each controller.
