Abstract:
Exemplary embodiments pertain to a system that can include a high-level controller coupled to a low-level controller for controlling a physical asset. In one exemplary implementation, the high-level controller executes a first finite state machine for controlling a power generation unit via a network. The low-level controller executes a second finite state machine that may have fewer states than the first finite state machine. The second finite state machine places the low-level controller in a default mode of operation for controlling the power generation unit under various conditions such as when the high-level controller is controlling the physical asset during a normal mode of operation; when the high-level controller is revising the first finite state machine; when the high-level controller is controlling the physical asset using a revised first finite state machine; and/or upon detecting a loss of communications between the high-level controller and the low-level controller.
Abstract:
A process control system having a backup controller which is substituted for one of a plurality of primary process controllers upon the detection of a failure of one of the primary process controllers. The substitution of the backup controller is controlled by a backup director which is arranged to sense the operation of a primary process controller and to transfer the operating data from the failed controller into the backup controller to enable the backup controller to take over the operations being performed by the failed controller.
Abstract:
In a method for actuating at least one actuator, two control units and a selection logic are provided, and each of the control units is designed to influence the actuator. Each of the control units performs a self-diagnosis, and each of the control units generates at least one activating signal as a function of the self-diagnosis. The activating signal indicates which of the control units is to be activated. The selection logic activates one of the two control units for influencing the actuator as a function of the activating signals.
Abstract:
A method is provided for selecting a plurality of program functions for providing repeatedly implemented functions, e.g., in a vehicle, ship or in an aircraft. The method includes determining a first total performance value based on recorded first single performance values and recorded first dependencies, determining a first total performance value based on determined second single performance values and recorded second dependencies, determining a cluster performance from the first total performance value and from the second total performance value, and the cluster performance value or at least one value determined from the cluster performance value is used for selecting the program functions or of other program functions for providing the repeatedly implemented functions.
Abstract:
A multi-channel control system includes a first primary control microprocessor and a second primary control microprocessor operable to control a device, and a first secondary control microprocessor and a second secondary control microprocessor operable to control the device. Each of the first and second primary control microprocessors and the first and second secondary control microprocessors are arranged as an independent control channel.

Abstract:
The present invention is related to a method for controlling a wind energy plant with plural control units, which perform control tasks in the wind energy plant, comprising the following steps: a) one priority at a time is assigned to the control units, depending on the control tasks they must perform, b) during the operation of the wind energy plant, the control units communicate continuously with each other and/or with a central communication unit, c) in case that there is a failure of a first control unit of the wind energy plant, a second control unit of the wind energy plant takes over the control tasks of the defective control unit, wherein the second control unit is selected depending on the priority assigned thereto and has the same as or a lower priority than the defective control unit.
