Lecture: "L9.1"
- 02-11-26/step
- Is there a way to draw out the step response based on the transfer function? ("step" is cheating!)
- 02-11-26/roll-off
- What specific modifications are necessary for the control transfer function of a PID controller to add the roll-off poles?
- 02-11-26/rlocus
- "Rlocus" in matlab assumes the system gain is the "free parameter". Is there a "simple" way to make it work for any parameters?
- 02-11-25/roots
- Are the zeroes for L=PC always called zeroes and the roots of L=PC always called roots?
- 02-11-25/rootlocuspoles2zeros
- What is alpha? What happens
when it goes to infinity? How come the roots go from the poles of PC to the zeros of PC?
- 02-11-25/rlslope
- On slide 9, where did the slopes and bounds come from?
- 02-11-25/poles
- Are the dominant poles the ones farthest to the right?
- 02-11-25/nyquist
- I just discovered that I don't know how to close Nyquist plots with poles on the jw-axis. Can you explain that again?
i.e. How do I determine which way to close the Nyquist plots if poles or zeros exist on the jw-axis?
- 02-11-25/loopbounds
- Is there any easy way in MATLAB to plot the tracking error bounds, phase margin bounds, etc that are used on the slides?
- 02-11-25/lead
- How would one implement a lead compensator? I know how to use the transfer function form, but what does that correspond to? For example, if C(s)=Ki/s comes from u(t)=Ki*integral(e(t)dt), what produces C(s)=K*(s+a)/(s+b)?
- 02-11-25/l
- Is L=PC or L=PC/(1+PC) for slide 6?
- 02-11-25/kd
- Is Kd an operator or a constant?
- 02-11-25/decreasenoiseamplif
- How does a pole at high frequency prevent PID amplification of high frequency
noise?
- 02-11-25/cancel
- Does cancelling poles/zeros make any difference at all?
- 02-11-25/asymptote
- Slide 8: The angle 360/(P-Z) is measured from where?
- 02-11-25/antiwindup
- How does moving a pole at zero to a small value prevent integrator windup?
