generation a train of impulses in simulink

Hi,Help please,I wanna to generate a train of impulses in simulink as input to my system .Actually my goal is to generate an impulse at any sample time(for example in T=0,0.5,1,1.5,...,Tend) with pulse duration of 0.001 second and variable magnitude that their magnitudes calculate simultaneously from feedback control rules. My question is how do i generate this train of impulses?

One option is to use the pulse generator. Instead of fixed values, use variables and define them in your system. Make sure you initialize them.

Another option is to create a custom block with clock input and your other inputs and create your own pulse generator.
