Difference Equation Block on SimulIDE

This example implements a difference Equation (up to $3^{rd}$ order) Block simulation on SimulIDE, as a Script (Angel Script).

This is done for implementing discrete system simulations on SimulIDE.

This repository includes 2 usage examples:

• Diff_Equ_test.sim1 RC discrete circuit simulation $f_s = 50 Hz$

• Diff_Equ_test_2.sim1 Unstable 3rd order system simulation $f_s = 50 Hz$

Usage

You have to copy the component's folder inside a one in the user data folder, for instance ~/User_data/testand associate it in Simulide. You can see how to do this in the official SimulIDE's Tutorials:

• User data folder SimulIDE 1.1.0

• Crear Componentes SimulIDE 1.1.0 (Spanish)

The difference equation constants:

$$ H(z) = \frac{B_0 \cdot z^{0} + B_1 \cdot z^{-1} + B_2 \cdot z^{-2} - B_3 \cdot z^{-3}} {A_0 \cdot z^{0} + A_1 \cdot z^{-1} + A_2 \cdot z^{-2} - A_3 \cdot z^{-3}} $$

can be set once the block Diff_Equ is added to the schematic, left-clicking on the component and selecting propertiesoption:
