Problem with SimScape Controlled Voltage Source
显示 更早的评论
Hi, I'm trying to simulate a simple RC divisor with Simulink SimScape.
As stimulation, I use Controlled Voltage Source block, controlled with the Signal Generator block. My problem is with frequencies higher than 10kHz, the amplitude of the signal changes.
This are some examples:
And the results:
If any more information it's required please ask me.

Hi Carlos
Check that the maximum step in your solver is small enough to capture the sine wave (10kHz). For example 10us. If the circuit is only resistive, amplitude should be the same regardless of frequency. However, if u have a capacitance, high frequencies are naturally ”filtered”.
Hope this helps / Juan

Can you share the model Carlos? I can look into it. Br Juan

Hola Carlos
El problema era simplemente que tenias activado el filtro en el elemento Simulink-PS Converter. Si restableces la configuracion inicial, el resultado es el esperado.
Siempre que sea posible, es preferible utilizar Simscape Physical Signals como estimulo ya que el problema matematico se resuelve mejor y no se requieren derivadas o filtrado en el S-PS componente.
Buena suerte / Juan
