The Absolute Basics of Collimator

The Basics of Collimator

  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

System Representation

Modeling the system in Collimator


  • Sim_Time = 10

  • Step_Value = 0.1

  • M = 1

  • b = 10

  • k = 20

  • Kp = 350

  • Ki = 300
