Cumulative sum in Simulink

hello ,

I need help, I'm trying to add my signals in simulink cumulative, I've tried to do it with a delay, with Cum sum in a Matlab function but it doesn't fit, does anyone have an idea and can help.

Answer 1

The Discrete-Time Integrator block can be configured as an accumulator.

Answer 2

[Fangjun Jiang]

For continuous system, feed your signal to an Integrator block.

For discrete system, add your signal with the output of a Unit Delay block, feed the output of the Sum block to the Unit Delay block.

i didn't undertand what should i do for Discrete System , can you please help me more.

[Fangjun Jiang]

using a Sum block and a Unit Delay block, add your signal with the output of a Unit Delay block, feed the output of the Sum block to the Unit Delay block.
