hey all, i'm stuck with the following designing problem (Control course) : 1. The problem statement, all variables and given/known data given the location of the poles , find rise time , peak time, percentage maximum overshot and settling time for each pole. pole are: 1 . pole at θ = 70 , ωn = 1 2. pole at θ = 70 , ωn = 3 3. pole at θ = 30 , ωn = 1 4. pole at θ = 30 , ωn = 3 2. Relevant equations 1. how to calculate tp, tr, max o.s and ts for each pole ? 2.how to find the damping ratio (zeta) ? 3. which one of the poles is the best ?
