  • Process controller output and alarm setting evaluation
    Publication number: 20060047351
    Abstract: A method for evaluating alarm settings and controller response time for continuous or semi-continuous processes that gives an indication of the ability of the controller to respond quickly enough to prevent alarms, and an indication of whether the alarm setting is within the normal operating region of the process. The technique requires only a history of alarm events, process measurements, and controller outputs.
    Type: Application

  • Evaluation of alarm settings
    Patent number: 6618691
    Abstract: A method for evaluating alarm settings for continuous or semi-continuous processes that gives an indication of the probability that an alarm will occur for values preceding the alarm value, and the probability that the process will continue on to a value following the alarm value. The technique requires only a history of alarm events and process measurements.

  • Performance assessment of controllers applied to integrating processes
    Patent number: 6594593
    Abstract: A method for determining the performance of controllers applied to integrating processes requiring only closed-loop data and equipment parameters. A numerical measure is calculated which is a comparison of the actual variation of the manipulated variable to the variation that would be expected if a controller which minimized the maximum rate of change of the manipulated variable while keeping the controlled variable within a specified range was used.

  • Performance assessment of non-deadtime compensated controllers
    Patent number: 6546358
    Abstract: A method for determining the performance of non-deadtime compensated controllers (i.e., PID) requiring only closed-loop data and an estimate of the process deadtime. A numerical measure is calculated which is a comparison of the actual variation of the process to the variation that would be expected if the process were controlled by an optimal non-deadtime compensated controller.
