Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I have a state space equation at hand.. This attached with this...

Now the term (theta double dot) is a positive step for 0,136 milli seconds and negative step for next 0,136 millisecond and 0 at all other times.

So that when I simulate I will get a graph as below:

This is the nature of the graph I am expecting.

Iam using Matlab ODE45 to solve this. It is pretty easy I think, but I cant figure out how to give this acceleration function.

I hope the question is clear. The values are

Omega = 219,

Zeta = 0,03

Gamma(i) divided by M(i)=0,01

theta double dot = -63 and +63 in the above said intervals respectively.
