hi, do anyone of you posses quadrature decoder/ rotary encoder simulink file?
i need to transform Phase A and Phase B signals from rotary encoder into angle, velocity, acceleration values.

Are you using SimElectronics? If so, there is an Incremental Shaft Encoder block provided. Have a look at the demo model elec_linact_implementation.mdl, which uses that block in the "Hall Effect Sensor" subsystem.

Thank you sir, As per Above demo the working of encoder will understand good. by open the file use full comment bellow
showdemo elec_linact_implementation

To transform quadrature signals A and B into angle, you only need a few basic blocks like logical operator, memory, sum, gain.
Start by placing 2 Pulse Generator source blocks in your model and configure them to generate the 2 quadrature signals. Then play with basic blocks to implement the simple algorithm to transform the 2 pulse into an angle. You should be able to find the algorithm for this in any mechatronics class book.

i'm using matlab version R2006a, doesn't seems to have SimElectronics embedded

SimElectronics is a separate product, which was first released in R2008b. It requires Simscape, which is an add-on product to Simulink, providing a foundation library of building blocks across multiple physical domains as well as an authoring language for creating custom components.

Hello! I have the same problem! I am using DC Motor model, and I have position on the output in this model. Now I would like to convert it to impulses of encoder. How can I do it? Thanks.
