  • Patent number: 8126575
    Abstract: A method for building robust model predictive controller universally applicable is presented based on the innate process characteristics independent of the method of control actuation. The method of universal MPC design permits proper configuration of requisite regulatory control loops for measured and unmeasured disturbance rejections consistent with the underlying innate process characteristics and their embedding within the overall process unit model predictive controller. The method of universal MPC design requires that manipulated variables process value based model (PV-based models) be used in control and optimization in place of the customary set point based models (SP-based models) or control output based models (OP-based models). The PV-based models are devoid of the manipulated variables regulatory controllers response and tuning. Based on the PV-based models, an alternate method of MPC called PV-based MPC is presented that is most robust and adaptable of possible three types of MPC.

  • Patent number: 7916140
    Abstract: Controlling a multi-variable process involves multi-dimensional representation of the values (Qa-Qh) of the process-variables (a-h) according to individual coordinate axes (Xa-Xh), and response based on historical values for the process-variables accumulated from multiple, earlier processes. An envelope (UL-LL) showing the best operating zone (‘BOZ’) for each process variable based on current values of the other variables is calculated from the accumulated historical values, and alarm conditions in which the current value of a variable lies outside the BOZ is rectified by changing the values (Qa-Qc) of manipulatable variables (a-c). Variable targets are achieved, alarms rectified and value optimisation realised using an inner envelope (UI-LI) derived from a subset of the BOZ-defining set of historical values. Where the alarm rate is low, operation is improved by narrowing the BOZ set to tighten the BOZ envelope (UL-LL) reducing an inner envelope where alarm rate remains acceptable, as a new BOZ.

    Abstract: A method is used for providing sensing data to a control system of a machine. The method may include providing a plurality of virtual sensors, each of which may have a model type, at least one input parameter, and at least one output parameter. The method may also include integrating the plurality of virtual sensors into a virtual sensor network; determining interdependencies among the plurality of virtual sensors; and obtaining operational information of the plurality of virtual sensors. Further, the method may include determining a first condition under which the virtual sensor network is unfit to provide one or more virtual sensor output parameter to the control system based on the determined interdependencies and the operational information; and presenting the determined first condition to the control system.

  • Patent number: 7447552
    Abstract: An automation device is disclosed, in which a multiplicity of physically distributed functional units communicate with each other by means of a common transmission protocol. The device has a microcontroller (110), which has a group of associated input/output connections which are connected to a resistor network. The resistances of the resistors follow a sequence, the resistance respectively being doubled from the less significant to the next most significant bit. Each input/output connection is actively switched to the associated logic level in order to output a first logic state and is connected as a high-impedance input in order to output the inverse, second logic state.

  • Publication number: 20080243273
    Abstract: A method and system of controlling operation of a diffusion appliance to treat the atmosphere within an enclosed space. The appliance may be programmed to operate according to a control scheme specifying a flow rate of liquid to a diffusion means and a periodic operation of the diffusion means. Control schemes may be associated with different volumes of spaces to be treated by the appliance. Anti-fatigue schemes may provide variation of the flow rate or periodic operation of the appliance. Initiation controls schemes may be used to start treatment of the space before the appliance is programmed to operate according to one of the control schemes.

    Abstract: An identifier which indicates a reason why a direct change is disabled upon application of a specific conflict resolution rule can be described in a conflict resolution rule description file (301). In case of a process executed when a UI is not displayed, a status variable list (304) that holds setup values and status values is accessed in place of an internal structure (305) to easily check if each setup item is enabled/disabled. Upon matching overall data, a start point list which lists setup items in a given priority order is loaded to execute conflict resolution in turn, thus resolving conflicts among setup items.
