    Abstract: An improved process-integral-derivative deadtime controller (PIDτ d ) utilizes an adaptive filter to compensate for mismatch between the controller deadtime and that of the process. The filter time constant is generated as a function of the manipulated variable signal noise level.

    Abstract: An improved system for tuning process control equipment applies a load change of amplitude δq to the process to effect a change in it and, therefore, in the controlled variable. Monitoring the response of the controller to that change, the system identifies an observed overshoot, OVS o , in the manipulated variable signal. From that overshoot signal and a predetermined theoretical overshoot signal, OVS τ , the system generates an optimum gain, K opt , as a function of the mathematical expression K opt = K * (1 + OVS τ ) / (1 + OVS o )
    where,
       K is the current gain of the automatic control subsection,
       OVS o is the observed overshoot, and
       OVS τ is the predetermined overshoot.

    Abstract: A self-tuning deadtime controller for adaptively adjusting one or several controller parameters during process control activities. The controller tunes, for example, the controller deadtime and the proportional band to optimize deadtime controller performance. The high performance of a deadtime controller is maintained even though the controller is incorrectly pretuned or if the process is subject to loads which change its characteristics.

    Abstract: Methods and apparatus for determining characteristics of a process -- such as primary and second time constants, dead-time, and gain -- apply a doublet pulse to the process and measure its response. By way of example, in one aspect there is provided a method for generating a signal, τ₁, representing an estimate of a primary time constant of a non-self-regulating process, in accord with the mathematical expression τ₁ (δmτ a ²)/A⁺; where A⁺ is a factor representing the time-wise integration of the controlled variable during the period when the doublet pulse is being applied.
