Examples of Control Systems

These are the files we used in class with the Sphero RVR for control and API

Examples to use Feedback control Loops

1. on/off control
2. on/off control with tolerance
3. proportional control
4. proportional-integral control
5. proportional-integral-derivative control, see PID controller on wikipedia

Simulations

Landing a Rocket - simulation on replit

Controlling a water valve - simulation on p5js

Controlling a robot arm to a specific angle just with torque - simulation on p5js

With an updated PID feedback control loop the specific angle are reached relatively fast, as this simulation shows. You can analyze the angle over time with Desmos:
