Foundation Block Set

Foundation Control Block Set

First Time Block:

The first time block sends a true signal out the first time the subsystem it is in is triggered. All other executions of that subsystem will have this block output a false signal.

Compare To:

The Compare To block allows the user to compare an inputted value vs. the given value in the mask. It will output a true signal when the values match.

Rising Edge:

This block detects a rising edge and sends out a value 1 when it does so.

Falling Edge:

This block detects a falling edge and outputs a value when it does so.

Derivative:

This block takes the derivate of an inputted signal.

Saturation:

The saturation block takes a min, max and inputted value. It then outputs the inputted signal when it is between the min max. When the inputted signal goes over the boundaries it outputs the min or max values.

First Order Low Pass:

The 'alpha' input is T/t. So when alpha = 1, the block simply passes the input through to the output, and when alpha = 0, the block forever holds its last output value.

Median Filter:

This filter block stores the number of data points that the user requests and gives the median of those values.

Time Since Enabled:

The Time Since Enabled block outputs the amount of time that has elapsed since the enable input has gone high. It holds its value when the enable input goes low, but resets again when it goes high.

Saturate Divide:

When the divisor is less than the numerator or zero, saturate and output one.

Integrator

The integrator block takes an incoming signal and integrates it. You can set a Min and Max value for the output. You can also enable the signal with the Rst signal, and it will output the IC value.

Simple PI, PD, and PID Blocks:

The simple PI, PD, and PID block set allows a user to quickly implement basic control loops.

The Universal PI, PD, and PID Blocks

The Universal PI, PD, PID blocks allow a user to quickly implement many types of control loops.

PID With Damper Terms:

This block helps the user implement a PID with Damper Terms.

Handoff Alpha

The Handoff Alpha block converts a boolean input signal to a more slowly ramping 'alpha' from 0 to 1.

Triggered and Enabled Counter Rising

The triggered and enabled counter count set up an increment. The triggered block does it on the rising edge of a signal, and the enabled block does it when it is enabled.

Variable Rate Limiter

The variable rate Limiter allows the user to dampen an incoming signal by limiting its rate of change in one time step.

Decayed First Order Filter:

The decayed First-Order Filter decays from the Initial Value to the Final Value when enabled.

Calibratable Foundational Operations

Polynomial Tunable

The Polynomial Tunable block allows the user to evaluate a polynomial using Horner’s Rule. The Polynomial is entered using a calibration block in the subsystem.

The Tunable 1st Order Low-Pass Filter

This is the 1st-Order Low-Pass filter with extra logic to have the alpha be a fraction of dT. If the calibration value for FilConst is lower than dT than the alpha value is one. If FiltConst is greater than dT, than the alpha is the dT divided FiltConst.

Saturation Tunable

This is the Saturation Block with the upper and lower limits as calibration values to be used in MotoTune.

Universal PD Tunable

This block is the Universal PD block with many of inputs and outputs as Calibration and Probe blocks to be used in MotoTune.

Universal PID Tunable

This block is the Universal PID Controller with many of the Inputs and outputs set as Calibration and Probe values to be used in MotoTune.

PID with Damper Terms Tunable

This block is the Universal PIDD controller with many of the inputs and outputs set as Calibration and Probe blocks.

Universal PD Tunable and Scheduled

This block takes the universal PD block and has many of the inputs and outputs set as Calibration and Probe blocks to be used in MotoTune. It also has lookup tables to schedule the signals.

Universal PID Tunable and Scheduled

This block takes the universal PID block and has many of the inputs and outputs set as Calibration and Probe blocks to be used in MotoTune. It also has lookup tables to schedule the information.
