# control-blocks

The goal of this project is to make a node based control system block diagram software. 

This will enable open source development and simulation of control systems.

![Diagram Example](/img/example_diagram.png)

## Current Capability

- Basic GUI and simulation for simple math / constants

- Block types:

    - Constant

    - Sum

    - Gain (only faciliator of feedback at the moment)

    - Mux (can add ports but not remove)

    - Display

- Can add/remove blocks and wires

- Saving and loading the diagram (only one filename supported right now)

## Dependencies

See `third_party` for a list of dependencies and how to install them.

## Active Work

- ODE solver

    - Using Boost for this.

- Improve feedback systems

    - This should be ready theoretically if each Dynamic system block actually implements `ApplyInitial()`

    - Unclear if basic blocks like sum and mux should have this feature, but it is likely they should

- Variables in a workspace

## Roadmap

The current work is focusing on Steps 1-3.

1. Basic GUI and scripting

    - Scripting will tentatively be in python, but might end up in C++

    - C++ will be used in the backend for speed optimization in the future.

2. Simulation for general dynamical systems (x_dot = f(x,u,t))

    - Series simulation only, no summing junctions

3. Simulation for linear time invariant (LTI) systems

    - State-space LTI systems

    - S-domain transfer functions

4. Diagnostics for LTI systems

    - Bode plot

    - Nichols chart

    - Nyquist plot

    - Pole-zero map

    - Step response

    - Impulse response

5. Basic block diagram algebra

    - Summing junctions

    - Feedback systems

    - Multiplexing

6. Advanced block diagram manipulation

    - I/O linearization

7. Controllers

    - PID

    - LQR

    f

8. Advanced control 

    - H-infinity

    - Model predictive control (MPC)
