The PID block formula in simulink and the standard PID formula is not the same。 The PID block formula in simulink：

The standard PID formula:

For example, a simple step response, when you build your own PID block, how to design PID program block ？

The parameters of the PID are same ：Kp=0.8 Ki=0 Kd=0.85 But the results will be some different。

I would like to know how to make the above two simulink procedures to express the same results？

PID Controller block supports two forms - parallel and ideal. Ideal form is very similar to the standard form you want.
