1) What are some alternatives to iterative design in control theory?
2) I have a certain plant transfer function PTF(s) that is higher order than two and non-unity numerator.
I want certain characteristics such as a certain damping ratio (zeta).
So I want approximate it as...
1) Why are Time Response Characteristic's Expressions derived from only from Zero State Equations?
NOTE: Nise Control Systems Engineering 6ed uses step inputs to derive Time Response Characteristics for 1st
and 2nd order ordinary differential equations...
NOTE: zero here does not mean the roots of the denominator in a transfer function
TRUE/FALSE -Please provide feedback- some answers are based on ODE example listed below
1/True) The Homogenous Solution is either zero or transient.; i.e. it can never be steady...
So, I was beginning to build a new and deeper understanding when I noticed that Particular Solutions can also be transient:
Thus in that scenario, I believe, the Particular Solutions can, jointly, represent the Transient Response. And as expected there isn't a Steady State Response because the...
-Does the Homogenous Solution represent the Transient Response?
Let me specify. For a N-DOF spring, mass, and damper mechanical system:
-Does the Homogenous Solution represent the Transient Response for given mechanical system?

- non zero initial conditions: x(t=0) = xo AND dx/dt(t=0) = vo
Ok I would agree with you too, however, the problem forces me to do one of two things to get the same result:
1) ignore the weight term. I think some call it the dynamic case.
2) the weight term is in fact apart of the total acceleration.
Tab = Tdc = sqrt(2)*m*a
If particles at B and C of equal mass m are connected by strings to each and to points A and D as shown, all points remaining in the same horizontal plane. If points A and D move with the same acceleration a along parallel paths, solve for the tensile force in each of...
Slip Plane: is the plane that has the densest atomic packing—that is, has the greatest planar density.
Slip Direction: corresponds to the direction in this plane that is most closely packed with atoms—that is, has the highest linear density.
θ = angle of the slip plane as...
Wow that makes a lot of sense! Though I still have some questions and responses to your answers.
Answer 1&2: dT/dy = 0; no temperature difference between top and bottom! It's the temperature difference that drives the heat flow.
Answer 3: Although the heat can still move in that additional...
1. My Conceptual Questions (5) is at 3.
Case 1: two dissimilar slabs of material (say slab 1 and slab 2) connected in series (bonded at their interface). There is a temperature difference: T1 @ slab1 and T2 @ slab2.
Case 2: two dissimilar slabs of material bonded together, i.e...
