Hey guys. I have a simulation problem. I don't know how to simulate(in SIMULINK) function which is not function of time. Here is a function: x(p)={konst. for -30<p<30} {0.2*INT(p*dt) for p<-30 or p>30} INT-integral
My problem is in "p" which goes from -100 till 100.In the following link I gave the task, the graph solution(which I need to get, but I dont know how) and my simulink solution which is not correct. http://oi47.tinypic.com/mkizxx.jpg
So to clarify, I dont know how to simulate this function in matlab-simulink

If it is not a time based simulation, then Simulink sounds not like the tool of choice.
There might be a fundamental issue with the undertanding of what a simulation is and what you need.

I know what you mean and this is nonlinear characteristics of servomotor. So to get this graph, I need to plot a function in Matlab-editor, no way to simulate work of servomotor in SImulink?

Of course you can simulate a servo motor in Simulink. You might want to check products like Simscape for the real stuff. There is already a Servo Motor block. For your application you might want to live with applying the charactristic by a lookup table block in Simulink.
