Using Derivates in simulink

Hi,

Is there any functin block doing deriviate in simulink ? I saw there is only du/dt as a numerical. Is there a way to do d/dt ?

Thanks, Henry

Hi Henry,

the derivative block is doing what its name says, namely estimating the derivative of the input signal. I don't understand what you mean by "d/dt" instead of "du/dt". From what do you want to compute the derivative, if not from a signal ...?

Hi,

For example: I my input signal is a current like I=A*sin(wt+phi) or W=1/2*C*V^2. Can I use du/dt block to deriviate this current or energy ?

Thanks, Henry
