Examples

Here is a project file showing an on off control system for a system such as an electric oven.

The setpoint is set via an analogue input which controls the desired temperature of the system.


In this first example the feedback is provided using the simulated load DSP component which simply takes a percentage of the last output and combines with a percentage of the new output.

This allows easy moddeling of systems such as ovens that heat up and cool down over time which allows you to see the system in action.

You assign a setpoint and then the system will get to temperature and then maintain the output by automatically switching the output on and off.


When the feedback is less then the setpoint minus the hysteresis then the output is switched on.

When the feedback is more then the setpoint then the output is switched off.

In this second example the feedback is provided via a temperature sensor component. This shows how you would do it with a real system using a sensor to complete the feedback loop.

As with other DSP components the raw signals and values can be seen in the data recorder and console windows.
