摘要： A converter system includes a rectifier, a DC link stage and an inverter connected in series. A control unit includes a slow reference frame angle determination unit that generates a slow reference frame angle θr,slow representing an angle that is slowly following a grid phase deviation, and a fast Phase Locked Loop generating a fast reference frame angle θr,fast representing an angle that is fast following a grid phase deviation. The control unit uses the slow reference frame angle θr,slow and the fast reference frame angle θr,fast to control the rectifier output current, and the fast reference frame angle θr,fast to control the inverter output voltage and to synchronize the inverter output voltage with the grid voltage.

摘要： A computer-implemented method for condition monitoring of an industrial drive. According to an aspect, the method includes: obtaining an image of a component surface of the industrial drive, wherein the image includes a first number of pixels; determining, using the image and at least one reference image for the component surface, a contamination index of the image, wherein the at least one reference image includes the first number of pixels; and triggering, in response to the contamination index being above a pre-determined first threshold, a maintenance warning.

摘要： A method of executing a request to an industrial control system, which runs in a protected domain and is configured to control one or more field devices. Each step of the method is to be executed on processing resources of a cloud domain (CD), an edge domain (ED) or the protected domain. According to the first aspect, a step of receiving, from a client, a message with a request containing logical actions and a step of authenticating the client are performed using CD resources. Next, a step of initiating a verification of the message and a step of checking whether the authenticated client is authorized to perform the logical actions are performed using ED resources. Then, a step of mapping the logical actions to physical actions and a step where the industrial control system is caused to execute the physical actions are performed using resources in the protected domain.

摘要： Methods, apparatuses, systems, computer readable media, and a computer product for detecting a gas leak of a gas tank. In a method, at least one inside temperature is determined for the gas tank based on a plurality of outside temperatures that are collected outside the gas tank, the at least one inside temperature being estimated for at least one inside position within the gas tank during an operation of the gas tank. A gas pressure within the gas tank under a standard temperature is obtained based on the at least one inside temperature. The gas leak of the gas tank is detected based on the gas pressure.

摘要： A system and a method, for assisting a user in programming a robot. Storage circuitry includes predefined possible values for a physical condition of at least two joints, the values being subdivided into two or more ranges. Processing circuitry is arranged to acquire a first path of the Tool Centre Point (TCP), receive, for each of a plurality of points of the first path and for the joints, a value associated with the physical condition at the respective points, determine which of the ranges the value is associated with, generate at least one additional path, associate each of the at least two joints to a respective path, and send instructions to a display, to illustrate the first path and the additional path, together with the information of which range the values are associated with at the plurality of points of the paths.
