go-control documentation
go-control is planned. It is the organisation the go-scikit parity plan names for what MATLAB’s Control System Toolbox, Simulink’s solvers, Mathematica’s control systems and Maple’s MapleSim offer. No library exists, no code is written and nothing is released: these pages say what the organisation will cover, in which wave, and what each part will be validated against.
Scope
LTI models and their algebra, time and frequency responses, stability margins, Riccati and Lyapunov equations, LQR and LQG, pole placement, discretisation, a solver for differential-algebraic equations, and, last, MapleSim-style symbolic acausal modelling. System identification and robust control are in the bibliography but not scheduled by the plan.
Plan
| Item in the plan | What | Wave |
|---|---|---|
| 12 | LTI models, frequency and time responses, Riccati and Lyapunov, LQR and LQG, c2d | 3 |
| 22 | model: symbolic acausal modelling, after the DAE solver and go-symbolic | 4 |
The plan is PLAN.md;
where each item stands is STATUS.md.
The facts behind the scope, the references and the validation measures are in
the roadmap’s
bibliography.
Control needs dense linear algebra that go-ndarray’s linalg does not have yet:
real Schur form with eigenvalue reordering, QZ and expm.
The planned packages
The names are provisional.
| Package | Status | What it will provide |
|---|---|---|
| lti | planned (wave 3) | models, algebra, poles and zeros, responses, margins |
| design | planned (wave 3) | Riccati, Lyapunov, LQR, LQG, pole placement, c2d |
| dae | planned (wave 3) | an IDA-type DAE solver |
| model | planned (wave 4) | symbolic acausal modelling |
Status
Nothing is released, so there is nothing to install. When a package is released its page becomes the package’s own documentation, and this site’s version label follows the newest release, as in the other go-scikit organisations.
