    摘要: A device includes a core structure including a first end plate and a second end plate. The first end plate and second end plate include a first portion and a second portion that extend from opposing sides of a third portion and include an increasing cross-sectional area configured to provide soft saturation properties in response to increasing electrical current. The core structure may further include a coil member and a core section. The core section is disposed between the first plate member and second plate member. The core section includes a first core member, a second core member, and a central disc member. The core section also includes a channel formed between the central disc member and the first core member and the second core member to enable the coil member to circumferentially wind around the central disc member.

    摘要: A method of estimating a radial deformation of a rotary shaft (290) in a loaded condition, comprising: recording a first radial displacement of the shaft's surface while rotating the shaft at a first angular speed corresponding to a relaxed condition of the shaft; on the basis of the first radial displacement, providing a first shape description representing the shaft's cross section in the relaxed condition; recording a second radial displacement of the shaft's surface while rotating the shaft at a second angular speed corresponding to said loaded condition of the shaft; on the basis of the second radial displacement, providing a second shape description representing the shaft's cross section in the loaded condition; and determining the radial deformation as a difference of the first and second shape descriptions.

    摘要: A control device (220a) for use with at least one further control device (220b) in controlling an industrial system (210), to which the control device and further control device are connected via a data network (240). On the one hand, the control device is operable to function as primary controller, wherein it feeds control signals (110) to the industrial system. On the other hand, the control device is operable to function as a backup controller, wherein it routinely performs a failure detection on the primary controller via the data network, and transforms into primary controller in reaction to a positive failure detection. The transformation from backup controller into primary controller is conditional upon verifying that a node (230) in the data network appointed as network reference point, NRP, responds to a call from the backup controller. A malfunctioning NRP can be replaced with a different NRP candidate at runtime.

    摘要: A computer-implemented method (100) for verifying the design of a function module (2) for use in a modular industrial plant (1), wherein the function module (2) comprises control logic configured to accept sensor data and actuate a physical process module such that at least one process quantity and/or state quantity of the process module can be kept near a desired set-point value, as well as logic to accept commands from a superordinate management system, and communication between logics, as well as between the function module (2) and the rest of the modular industrial plant (1), is by input/output channels (31-35) representing parameters and/or variables, the method comprising the steps of:
    • obtaining (110) a ruleset (4) comprising at least requirements for I/O channels (31-35) and their connections that are necessary conditions for the function module (2) to perform its intended function in the modular industrial plant (1);
    • checking (120) whether the input/output channels (31-35) of the function module (2) and their connections meet the rules in the ruleset (4); and
    • in response to determining that at least one rule in the ruleset (4) is not met, determining (130) that the design of the function module (2) has an error, and preventing (190) use of the function module (2) in the modular industrial plant (1).
