want to convert rotary encoder pulses into angle for DC motor

I'm using an rotary encoder to read the rotation of a DC motor with gearbox

i want to use Simulink to read channel A and B convert it to angle and then adjust control to the motor

unfortunately there is no block in Simulink to do that

i had the idea to read the 2 channels positive edge into edge triggered counter but I don't know how to create the condition statement in Simulink to increment and decrement the counter

Hello Yousif,

this example has an implementation in Simulink for decoding a pulse stream. It's in the hall effect sensor subsystem.

You can use a switch to add a positive or negative value depending on the value's detected: https://www.mathworks.com/help/simulink/slref/switch.html
