Various algorithm to control things

Automation

Various algorithm for Systems & Control operations for Microsoft MakeCode editors.

How to use this library?

In your MakeCode editor, click on the gearwheel menu and click "Extensions", search for "automation" and select this project.

PID controller

A Proportional-Integral-Derivative control is a classic control structure in automation. The user needs to define 3 gains (Kp, Ki, Kd) to tune the controller.

See Reference: Feedback System, Karl Johan Astrom & Rickard M. Murry

let v = 0;
automation.pid1.setGains(1, 0.01, 0.001);
for (let i = 0; i < 10; ++i) {
    v = automation.pid1.compute(0.1, 5);
}

Behaviors

An example of Behavior-based robotics control system.

Moving Average Filter

let r = 0;
for (let i = 0; i < 10; ++i) {
    r = automation.movingAverageFilter1.filter(Math.random());
}

Supported targets

• for PXT/maker
• for PXT/adafruit
• for PXT/codal
• for PXT/ev3

pxt-automation's Issues

What goes in the timestep parameter?

The example in the readme has a constant going in the timestep parameter, but for that matter, it also has a constant going into the y parameter, which is not how this component would actually be used.

A more illustrative example would be helpful.
