Question 1

For a faster response, what change in our characteristics do we want?

Answer 1

We want a higher phase margin frequency -> to achieve this we want a higher natural frequency and a lower rise and peak time.

Question 2

For a less oscillatory response what do we want?

Answer 2

Higher phase Margin so higher damping and smaller overshoot.

Question 3

What can we assume the bandwidth frequency is?

Answer 3

Phase Margin frequency.

Question 4

For a type 0 system what is the steady state error?

Answer 4

1/ 1 + Kp

Question 5

For a type 1 system what is the steady state error?

Answer 5

1 / kv

Question 6

For a type 2 system what is the steady state error?

Answer 6

1 / Ka

Question 7

What happens when we add proportional gain to the system?

Answer 7

It will increase the static error constants

Question 8

How can we decide what proportional gain to add to a system?

Answer 8

By finding the old steady state error, and then dividing our desired steady state error by it.

Kc = New Ess / Old Ess
