Answers

1
Linear systems...
only have one equilibrium point
never have any equilibrium points
sometimes have multiple equilibrium points
always have multiple equilibrium points
2
An observer...
estimates the full state based on measurements
estimates the full state based on the laws of physics
estimates velocities based on position measurements
makes the state estimate go to zero
3
If you can measure position, why not just differentiate to find velocity?
No, you totally can. Velocity is the derivative of position, right?
Because even small noise can make big changes after you differentiate
Because it takes too much computational power
No, you totally can, you just need a fine enough timestep.
4
The poles of (A-BK) are the poles of the closed-loop system in full-state feedback.
False
True
5
Every nonlinear system can be linearized
True
don't pick this answer, i couldn't think of a fourth one
False
Not enough information to decide
6
A first order linear system has B = -1. It is controllable.
Idk, I can't think of a fourth option, don't pick this one
False
Not enough information to decide
True
7
If a system is controllable, it is also observable.
False
True
