Lecture: "L5.1"

02_10_28/stepr
Why do they call it "step response"?

02_10_28/frns
Is full rank equivalent to nonsingular?

02-10-29/thetaclarif
On slide 6/7 and in homework 4, problem 2, is q labeled correctly to be zero in the "up" position?
(I thought one of the TAs said it should be zero in the down position).

02-10-29/positivedefinite
For a matrix P, how exactly is the expression P>0 defined?

02-10-29/eigenphysical
What is the physical interpretation of arbitrarily changing the eigenvalues? Is it possible to do in a real system?

02-10-29/discretecontrol
Does controllability generalize to discrete systems? Do you have to be able to reach the desired state in 1 time step?

02-10-28/toofast
The lecture seemed very fast.

02-10-28/thm
Why is the following theorem true: "Linear system is controllable iff the controllability matrix is full rank" ?

02-10-28/slide8
On slide 8, is the curve x1(t) unique?

02-10-28/sim2
How do we set initial conditions in Simulink?

02-10-28/sim
Do people use simulink in the "Real World"?

02-10-28/review
I can't make it to the review session this Friday. Could you tape that please?

02-10-28/nlcontrollability
If a linearization is controllable, is the full nonlinear case always controllable also? Does this apply for any initial conditions or only a limited region?

02-10-28/mttopics
What topics are covered by the midterm? How much linear algebra, theory, or applications are on the midterm?

02-10-28/mtbooks
Are non-course linear algebra books or differential equation books OK for the midterm?

02-10-28/midterm
When / where do we pick up the midterm if we are taking CDS 101 and we don't come to the Wednesday lecture? Also where do we buy blue books?

02-10-28/howtoeqmpoint
On HW3, I couldn't find the eqm. points besides (0,0) and (77,95) in the predator prey problem - what are they and how do we find them?

02-10-28/fullrankint.html
What does "full rank" mean when applied to the integral in the convolution integral?

02-10-28/fullrank
Please explain full rank, definition. What it entails.

02-10-28/cont2
Are degenerate states in the controllability matrix always physically realizable?

02-10-28/cont
If a system is not controllable, how does one find what "isn't controllable", i.e. what states can't be achieved. Is it the null space of the controllablility matrix?

02-10-28/LQR
What do Q and R represent(in slide 15)?
