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.

thanks.

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.

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.

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.
