MATLAB: Analog circuits in Simulink

Question

I want to implement simple circuits such as RC circuits in simulink with input from a signal generator. Unfortunately, I always encounter errors such as "no solver block" etc. Here's the pic of the model: http://img713.imageshack.us/img713/5582/96748583.png

I am new to Simulink, so this might seem a bit silly but any help is welcome.

Answer 1

The error seems to indicate that you are missing a solver block, but you have one in the image you've attached. For the case of the attached image, I would expect a "missing reference node" error. You need to include at least one Electrical Reference in a Simscape electric system.

Also I noticed you are trying to connect a regular Simulink Scope to your circuit. To measure a value in the circuit you need to use an Electrical Sensor such as a Current Sensor or Voltage Sensor and then convert that signal to a regular signal using a PS-Simulink Converter block, then you can send that signal to a Scope.

It might be easiest to start from an example. Try loading ssc_new_elec by typing that at the MATLAB command prompt. That brings up a basic model and a helpful palette that you can use to quickly build up more models.
