Abstract
A method and system for a control circuit are provided. The circuit includes an integrating counter coupled to a process wherein the integrating counter is configured to integrate over time a process parameter signal received from the process and to generate a trigger signal when the integrated signal equals a predetermined count. The control circuit also includes a transition controller electrically coupled to a respective control element and configured to receive the trigger signal generated by the integrating counter.
Claims20
A control circuit comprising:
- an integrating counter coupled to a process, said integrating counter configured to:
- integrate over time a process parameter signal received from the process;
- and
- generate a trigger signal when the integrated process parameter signal equals a predetermined threshold;
- a transition controller electrically coupled to a respective control element and configured to:
- receive the trigger signal generated by said integrating counter;
- and
- switch the control element based on the received trigger signal.
A method of controlling a process system, said method comprising:
- integrating a process parameter signal to generate an integrated parameter value, the process parameter signal including a process parameter component and a disturbance component;
- comparing the integrated parameter value to a predetermined threshold;
- and
- triggering a switching of a control device when the integrated parameter value equals the predetermined threshold.
A process system comprising:
- an input assembly configured to:
- receive a process parameter;
- and
- generate a process parameter signal relative to the process parameter, said input assembly comprising at least one converter;
- an output assembly comprising a respective control element coupled to a respective process element;
- and
- a control unit configured to monitor a convergence of the process parameter signal towards a setpoint, the control unit configured to trigger a transition in an output of said output assembly prior to the process parameter signal reaching the setpoint.
