CDS 101/110a | Schedule | Recitations | FAQ | () |
This page contains frequently asked questions for CDS 101/110. You can find FAQs for individual lectures and homework sets on the topics page for each week, available via the course schedule.
Week 1
- Can you make the graphics bigger so that we can see them?
- Can you speak more slowly?
- How are stability, performance, and robustness different? They seem very similar
- How do I create a FAQ for CDS 101/110?
- How would you make the dynamics in the cruise control example more realistic?
- I did not understand robustness
- I didn't catch the fly video. Is it available online?
- Is a high gain good in the speed control example?
- Is control a type of negative feedback?
- Is it possible to take CDS 110b without taking CDS 110a?
- Is it true that feedback systems are in closed loop by definition?
- Is kp (the gain of the system) dimensionless?
- Is there room for learning in control systems theory?
- Latency wasn't mentioned in the example; does it affect robustness?
- Please turn the AC higher.
- Should we bring our computers with Matlab installed to the review Friday?
- The additional material and schedule of cds210.
- The last few slides went by too fast
- What do you mean by "gain" in the speed control example? What relation to sensing does it have?
- What is an example of an open loop system
- What is the schedule for 101 in the 4th, 6th, & 8th weeks?
- What should we do with unsused Mud Cards?
- Where can I get a more detailed description of how the flyball governor works?
- Why does instability imply poor performance?
- Are there any advances in applying feedback modeling to social systems other than in an economic sense?
- Can I turn my homework by email (pdf file)?
- Can the environment be considered a system state?
- How do I save the mp3 files?
- How does feedback help the X-29 experimental aircraft?
- In lecture 1.2, y(x) was used as a function of the state variables. Is y a generic function of vector x?
- It's a bit unclear to me when you talk about "error" in PID control
- What are methods for determining errors in a real system?
- What is fuzzy logic?
- In problem 1 (CDS 110)/problem 2 (CDS 101), download cruise-ctrl.mdl, NOT cruisedyn.m
- Problem 1 -- Do I need to know exactly how a device works to use it as an example?
- Problem 2b -- Does this mean exactly or at least fifty percent?
- Problem 4 -- Do I have to sum n i(t)?
- SIMULINK License
- What is the policy for using symbolic manipulation on homework sets?
Week 2
- Can a Lyapunov function be used to show/prove a system is unstable at an equilibrium point similar to the way it can be used to show asymp stability?
- How do we read the simulated predator-prey graph?
- How is the Internet a feedback system?
- I'm a 101/110 student. Can I sit in on the 210 lectures on Fridays without being enrolled in 210?
- In slide 12, what is special about the red cycle as opposed to the blue curves?
- In slide 9, why did you only linearize around the downward equilibrium point?
- Is q1 a function of time
- Is there any open source software we can use instead of MATLAB?
- What are the Di parameters in the power grid model?
- What does the 45 mean in ode45?
- What does the at symbol mean in front of a function in matlab?
- What is a finite state machine and how does it relate to the traffic example?
- What is the significance of having eigenvalues that are 0? I think I heard you say "in that case you don't know anything". Does that mean you cannot determine if the system is stable or asymptotically stable?
- What's the difference between control "over" network and control "of" network?
- Where can I find a theoretical definition of dynamical system?
- Why is dB defined as 20log 10?
- Why was there only one damper in the mass/spring model?
- You mentioned "aggressive" dynamics a couple of times. Please define. How/when is it useful?
- You said spiraling out to a bounded circle is unstable, but doesn't that still satisfy the epsilon-delta condition of stability? Or are there limits on epsilon?
- CDS210 Problem 4 typo
- Do we have to consider complex states when trying to find equilibrium points analytically?
- In problem 3 (CDS 110), please use a different V2(x).
- Phaseplot
- Problem 1 -- Can I use Maple or Mathematica to solve this?
- Problem 1 -- Why don't the units work?
- Problem 2 - Actuator block
- Problem 2 -- Saturation of signal u
- Problem 2b -- Do I need to include the controller and feedback?
- Problem 3 -- Does "output get smaller as k gets larger" mean it gets more negative or more closer to zero?
- There are some problems with Ex 6
- Why are the initial conditions of the integrator and engine in hw1cruise.mdl set to 55*50?
