1. The problem statement, all variables and given/known data Sampled Data system Using the forward Euler integration algorithm, convert these differential equations to a set of difference equations. Use a stept size of deltaT = 0.1s. 2. Relevant equations x1(dot) = x2 x2(dot) = x3 x3(dot) = -2x1-3x2-4x3 y = 7x1-5x2 3. The attempt at a solution Nothing relevant! I have scribbled around and played with stuff from wikipedia, mainly with the form yn = yn-1+deltaT*f(tn-1, yn-1), but to no avail. Do I start with: dy/dt = 7x1(dot)-5x2(dot) and so on? I end up in a loop as soon as iI get to the derivation of x3. IIt doesn't feel like I am on the right path. What I am looking for is the starting point (so far). I learned about this stuff in school about 5 years ago, but I haven't touched it ever since. Now I wanted to do some reading on system modeling and I thought I could give a go to the exercises in the book as well. First attempt, first failure. Help!
