Toolkit

5 tools, 2 available
ToolStatusWhat it does
RGA Correction Tool AvailablePaid accounts Analyse and regularise gain matrices via Relative Gain Array analysis. Supports 2×2 and 3×3 sub-matrix analysis. RGA correction optimises the matrix to minimise gain deltas while achieving a target RGA number.
Data Cleaning Utility AvailablePaid accounts Import time-series process data, interactively remove bad ranges, detect flat-line and outlier periods, and export clean datasets for use by other apps.
Loop Analyser In development Evaluate PID tuning and take the guesswork out of quantifying the benefit before and after a tune.
Process Model Identification In development Identify a first-order plus dead-time process model from closed-loop historian data, then play with PID tuning to observe the expected control response.
Loop Sandbox In development Build control schemes as block diagrams and simulate them in your browser. Analyse and convolve multiple Laplace models into a single process model.
