20080215163 | Method For Operating a System - A method for operating a system, as well as a computer program and a computer program product for executing the method. In the method for operating a system, which includes a plurality of control units, in the event that a special state exists for one of the control units, at least one of the other control units is informed about it. | 09-04-2008 |
20090132061 | SYSTEM AND METHOD FOR RECOVERING FROM TRANSIENT FAULTS IN AN IMPLANTABLE MEDICAL DEVICE - A system and method is disclosed for system fault recovery by an implantable medical device which employs a global fault response. The system enables the device to consistently recover from transient faults while maintaining a history of the reason for the device fault. Upon detection of a fault, the primary controller of the device signals a reset controller which then issues a reset command. All sub-systems of the primary device controller are then reset together rather than resetting individual sub-systems independently to ensure deterministic behavior. | 05-21-2009 |

20090299492 | Control of connecting apparatuses in information processing system - In an information processing system, a first system control apparatus of a first information processing apparatus causes a first connecting apparatus to disconnect from the first shared storage apparatus, causes a second connecting apparatus to disconnect from the second shared storage apparatus, causes a control part to start up the first information processing apparatus, causes another first connecting apparatus used to replace the first connecting apparatus to connect to the first shared storage apparatus, and causes the second connecting apparatus to connect to the second shared storage apparatus. In the information processing system, a second information processing apparatus includes a second system control apparatus and a third and fourth connecting apparatuses used to connect to the first and second shared storage apparatuses, respectively. | 12-03-2009 |
20090306793 | Communication apparatus and communication apparatus control method - A communication system is installed in information home appliances controlled by an operation system connected to an IP network. The communication system includes a first communication apparatus connected to the IP network; and a second communication apparatus connected to the first communication apparatus. The first communication apparatus includes a determining unit for determining, based on an attribute included in a search signal transmitted from the second communication apparatus in order to search for the first communication apparatus, whether the first communication apparatus can control the second communication apparatus; a search-signal response signal generating unit for generating and transmitting, to the second communication apparatus, a response signal in response to the search signal in the case the determination of the determining unit is affirmative; and a registering unit for registering the second communication apparatus as a control target based on a connection request made by the second communication apparatus. | 12-10-2009 |
20100198364 | Configurable Multivariable Control System - A method for controlling an industrial process, such as a paper machine, is devised to handle multiple manipulated and controlled variables of the process. The method includes making available for selection a plurality of different multivariable sub-control systems for controlling the process. A user interface table is generated and displayed showing configuration information about the plurality of multivariable sub-control systems. A selection of one of the multivariable sub-control systems is received through the user interface and used by the computer system for configuring the multivariable control system and performing control calculation for the multivariable control system. | 08-05-2010 |
20110153031 | COMPONENT CONTROL SYSTEM - A system and method are provided for managing a plurality of components. The system can comprise a first component having a first operational parameter and a second component having a second operational parameter. The operational parameters of the first and second components can be modified in response to signals regarding the other one of the first and second components. Further, a component of the system can operate with a delay period during which an operational parameter of the component does not change in response to an operational parameter of the other component, but after which the operational parameter of the other component can cause a change in the operational parameter of the component. | 06-23-2011 |
20110288657 | METHOD AND SYSTEM FOR THE PROTECTION OF AN ELECTRIC LINE FOR RAILWAY SIGNALS - A system for the protection of an electric line for railway signals that comprises a computerized central apparatus (ACC) connected to a plurality of peripheral posts (PP). Each peripheral post comprises at least one plant-controller electronic card (CdE), which controls a plurality of plant-interface cards (IE) that supply the plants (E) directly, via a field bus (B | 11-24-2011 |
20120173002 | TWO-DEGREE-OF-FREEDOM CONTROL HAVING AN EXPLICIT SWITCHING FOR CONTROLLING CHEMICAL ENGINEERING PROCESSES - The present invention relates to a method for performing closed-loop control of process-engineering processes, in which setpoint value trajectories are provided for closed-loop control variables, closed-loop control variables and further state variables of the process are detected, control errors are calculated and closed-loop controller manipulated variables are calculated therefrom by means of a control algorithm, and in addition pilot controller manipulated variables are determined, resulting manipulated variables are calculated from closed-loop controller manipulated variables and pilot controller manipulated variables and are set in the process, wherein the structure of the control algorithm and/or of the pilot control are/is changed as a function of closed-loop control variables, further state variables and/or setpoint value trajectories. Furthermore, the invention relates to a closed-loop control device and to a computer program for carrying out the method. | 07-05-2012 |
20130131832 | Method and Apparatus For Analogue Output Current Control - This invention relates to an apparatus and method for output current control in an Industrial Process Control System. The output module comprises two management units each of which calculates the current demand for the module independently from one another. One management unit controls an output current controller whilst the other unit monitors the current produced by the output current controller against an independently calculated demand. The output module has multiple output modules. However rather than one module providing a backup for the other modules, or alternating between use of each module, in normal operation, each module provides a portion of the required output current, the total output current being equal to the sum of the currents output by each module. In the event of failure on one of the modules, the other module or modules switch to providing the total current required and the failed module is switched to a fail safe mode by using an isolation circuit to switch off the output current from that module. | 05-23-2013 |
20130197672 | Pass-Through Controller for Cascaded Proportional-Integral-Derivative Control Loops - A cascade control system includes pass-through controller and a Proportional-Integral-Derivative (PID) controller, wherein the PID controller controls a first output of a device to generate an input to drive the device. The pass-through controller provides a setpoint to the PID controller and controls a second output of the device. The first output and optionally also a derivative of the first output is passed to the pass-through controller so that a pass-through control algorithm can be implemented that results in the input to the device only having terms of the second output, thereby avoiding dynamic interaction between the control loops of the pass-through controller and the PID controller. | 08-01-2013 |
