From transfer function to digital controller, on a single model. Classical analysis, state space and discrete control powered by a native numerical engine.
The web app is experimental and may run slower. For the best performance, use the Windows version.
For engineers who design and validate control loops, and for those learning to: from classical theory to digital control.
Block diagram editor with subsystems and persistent projects.
The metrics you need to validate a loop, computed and traceable.
Complete root locus with interactive readout at every point.
From specifications to compensator, no spreadsheets needed.
From TF to SS and back, with control and estimation.
Sample, discretize and design in a single workflow.
Simulate the full diagram or validate the controller on physical plants.
Fast, accurate computation where it matters.
Modeling, analysis, design, simulation and digital implementation on the same system. No exporting or copying data between tools.
Drag and connect blocks; the suite derives the equivalent transfer function of the diagram.
Illustration generated with the same equations the suite uses.
Bode, Nyquist, poles and zeros, margins and a stability verdict, all linked to the same model.
Illustration generated with the same equations the suite uses.
Set Mp, ts, GM or PM and get compensators and PIDs that meet them, with the root locus in view.
Illustration generated with the same equations the suite uses.
Nonlinear simulation with saturation, delays and discrete blocks, with metrics computed instantly.
Illustration generated with the same equations the suite uses.
Discretize, compare against the continuous design and verify stability in the z-plane before implementing.
Illustration generated with the same equations the suite uses.
Adjust ζ and ωn and see in real time how the poles, the response and its metrics change.
Prioritized by what real control work demands. Each phase ends with tests and an example project that exercises it.
Time response, error, stability, root locus and frequency, with every metric made explicit.
Lead, lag and PID via root locus and frequency response.
Sample, discretize, design and verify in the z-plane, end to end.
Conversion, controllability, minimal realization and reference tracking.
Build the model from the physical system or from measured data.
From a validated design to code running on the device.
Multivariable, robustness, nonlinear, adaptive and MPC.
Tables and math tools at hand, without leaving the app.
The interface is also evolving into a complete workspace, with persistent navigation, desktop shortcuts and touch support.
Every release documents the relevant changes to the suite.
The complete SISO loop workflow on a single model: modeling, analysis, design, simulation and digital implementation.
Internal build. New canvas engine and native C engine build support.
Internal build. Tablet-oriented interface, C99 numerical engine and continuous and discrete SISO analysis.
Internal build. First diagram editor, classical analysis and simulation with physical plants.
Available for desktop, tablet and the browser. Follow the roadmap to see what’s coming next.
The web app runs with nothing to install, but it is still experimental: you may notice performance issues, since it does not use the native numerical engine. For everyday work we recommend the Windows version.
