A method for controlling a human-robot collaboration (HRC) system wherein the HRC system includes at least one manipulator having an end effector. The method includes using the end effector in a first operating mode, wherein the end effector is operated with reduced power; monitoring whether a desired object is manipulated when the end effector is used in the first operating mode; and increasing the power used to operate the end effector in order to use the end effector in a second operating mode when the monitoring indicates that the desired object is being manipulated.

A motor control system includes a motor, and motor control circuitry that controls driving electric power for the motor based on a driving state quantity of the motor, and upon input of a safety request signal from outside the motor control circuitry, monitors a relationship between a driving state quantity and an operation monitor pattern selected from multiple kinds of operation monitor patterns using multiple simultaneously functioning safety function software modules.

A method for monitoring a control of a parameter of one or more devices or systems in an oil or gas production site includes receiving process data, the process data being a result of the control of the parameter of the one or more devices or systems in the production site; smoothing the process data using a polynomial filter while preserving features of the process data to obtain smoothed data; and applying a pattern recognition algorithm to the smoothed data to determine whether there is a malfunction condition in the one or more devices or systems.
