why simulink has noise while ode45 dose not?
显示 更早的评论
Hi friends
I have developed a code based on ode45 and a similar simulink. the similink scope shows some noise in the results while ode45 does not. why is there this difference and how can I eleminate the noise from the scope in simulink?
I have attached the figures

Without code or Simulink model it is hard to tell what is exacly the reason. In case that the noise is numeric and should not be there, you probably need to change the solver settings in Simulink (Simhlintaion-->Model Cofigureation Parameters->Solver). Try, for e.g., reducing the tolerance.
