    Ziegler-Nichols speed

    Desired response performance of the PID parameters.

    Name Value Description
    Fast 0 Specifies a fast response performance. Faster response generally results in a smaller rise time.
    Normal 1 Specifies a normal response performance.
    Slow 2 Specifies a slow response performance. Slower response generally results in less overshoot.

    Default: Fast

    datatype_icon

    type of controller

    Parameters to return as PID gains.

    Name Value Description
    P 0 Returns only the proportional parameters.
    PI 1 Returns the proportional and integral parameters.
    PID 2 Returns the proportional, integral, and derivative parameters.

    Default: P

    datatype_icon

    stimulus signal

    Stimulus signal for the system.

    datatype_icon

    response signal

    Response signal of the system.

    datatype_icon

    closed-loop?

    A Boolean that specifies whether the system is a closed-loop system.

    True The system is a closed-loop system. The node estimates open-loop parameter values based on the closed-loop values the node identifies from the input signals.
    False The system is not a closed-loop system.

    Default: False

    datatype_icon

    controller gain

    Initial value for the controller gain.

    This node uses this input to calculate integral of PID gains.

    Default: 0

    datatype_icon

    dt

    Loop-cycle time or interval, in seconds, at which this node is called.

    dt must be greater than zero.

    Default: 0

    datatype_icon

    PID gains

    Proportional gain, integral gain, derivative gain, and filter coefficient parameters of the controller.

    This output can return a cluster or an array of clusters.

    datatype_icon

    proportional

    Proportional gain of the controller.

    datatype_icon

    integral

    Integral gain of the controller.

    datatype_icon

    derivative

    Derivative gain of the controller.

    datatype_icon

    filter coefficient [a]

    Derivative lowpass filter coefficient of the controller.

    datatype_icon

    stimulus operating point

    Stimulus offset for the plant.

    datatype_icon

    response operating point

    Response offset for the plant.

    datatype_icon

    plant parameters

    Gain, time constant, and dead time of the plant.

    datatype_icon

    Plant Gain (K)

    Process gain (K).

    datatype_icon

    Time Constant (T)

    Time constant (T), in seconds.

    datatype_icon

    Dead Time (L)

    Dead time (L), in seconds.
