I am trying to fairly compare different control design approaches. As an example, below I present two similar but different techniques which are:
- Control system with state feedback
- Control system with state feedback and observer
The plant input is voltage.
What I have done
I designed both systems on Simulink, with the idea that I would be able to check the input to the plant and get an RMS and current reading to get instantaneous power.
Both plants are the same, and so is the input.
I am trying to get a voltage and current reading after the summing junction, before entering the plant so I am using the Multi-meter block by Simulink. However I get no available measurements:
Am I using the wrong tool to get read the VRMS and current?
Any suggestions on how I can compare power requirements for these two different control design approaches would be appreciated.
This could be an alternative technique: What is the output of a PID controller (or any controller in general)?
