The Absolute Basics of Collimator

The Basics of Collimator

  1. 1.
    In your project dashboard, create a new project:
2. In your project, create a new model. You can learn more about models here. It opens automatically once you’ve given it a name:
3. In the model canvas, add a signal block by dragging from the library on the left into the canvas area:
4. Click the squiggly icon upper right of the ramp block to show the simulation result for that block in the visualizer, then click the Play button:
The visualizer and console can be opened by clicking their icon in the lower banner, they can be closed by clicking the X in the right side of the banner:
Now you can try adding more blocks to see what dynamics they produce.

Simple example of a PID controller built in Collimator

A PID is a commonly used control loop mechanism employing feedback. It uses the weighted sum of the following to adjust the process via a control element:
  • P (proportional): depends on the present error
  • I (integral): accumulation of past errors
  • D (derivative): prediction of future errors, based on current rate of change
