Homework Statement
see attached, question 8a and b are what I'm attempting. I've also attached the VERY brief course notes that I'm required to work with.
I know Tc= 8 seconds from the graph (0.13minutes)
Gain set to 4. is PB therefore 100/4=25%?
I'm struggling to calculate the ratio of successive amplitudes. If I figured this out I'd be able to calculate lnX/2π (see relevant equations below)
Homework Equations
Ti=Tc/2√1+Δ^2
Td=Tc/8√1+Δ^2
Tc=period of oscillation in minutes.
Ti=Integral action time in minutes.
Td=Derivative action time in minutes.
Δ= lnX/2π (where X is the ratio of amplitude expressed as 1:X
The Attempt at a Solution
Any help would be greatly appreciated.
