Great explanation, but one question: What would you do in the case of a 4th order controllable MIMO with 2 inputs? Because the K matrix will become [k_11 to k_14; k_21 to k_24], which is too many unknowns for two equations? Thanks!
Thank you for your video. I have a question about the full state feedback control. I see that inverted pendulum is an example of FSF, but I see them usually try to balance the pendulum at 0 deg (wrt verticle axis). I want to ask if I can use FSF to first move the pendulum angle from 0 to 30, e.g, then maintain it at 30 deg?
AE511: Chris, I loved the end of the video with your dog. Can you clarify something for me? If a system is "controllable", does that mean that the system can be driven to ANY state? This sounds to me like no real system would be controllable. The range of any real actuator will be limited. Take your mass spring damper system with 2 actuators as shown in the video for example. You showed that this system WAS controllable, but in reality these two actuators would not be able to extend to any infinite length; maybe their range is limited from 0 to 12 inches of travel each. If we add that constraint, does the system remain controllable? The system would be unable to reach any desired position in the x-y plane.
Hello Dr. Lum, I am looking for a teaching on MIMO state space systems that have augmented states for including integral error. Where to place poles and how to place integral poles (doesn't seem to work with multiple zeros). Also doing the complete design all the way through getting discrete time gains for implementation on a microprocessor. This seems to be a very common thing that would be done but I have searched and searched and cant find a resource for this. Most stuff is just how to place continuous time proportional poles once you know where they should go. In my opinion this teaching is ubiquitous but misses the mark in practicality by a long shot.
AE511: very interesting controller(regulator). My only question is how does Matlab arbitrarily choose where to place two of the four indices in our K matrix in the instance when you have more unknowns than equations?

AE511. With the Matlab examples it would be super helpful if you could leave them up for a little longer - I'm having to go back and forth (and youtube doesn't have a 10-second-rewind function!) in order to follow along. Thanks.
Thanks professor, great video. So does FSFB only work as a regulator, or can it be used as a controller to drive the system to some reference state instead of just the zero states?
Great question. In this case, we are considering it a regulator but there are many ways that you can use FSFB to track a signal. These are topics for another discussion but if you're interested there are things like LQR and LQ trackers that can achieve this.
Dear Sir, Thank you for teaching us this difficult thing so nice and easy way. I am doing some project on which I want to perform reduced order state feedback. Can you please mention some book in which I could find it in a little elaborate way? If you kindly mention the name of any book or reference or the theorem or even some key words, it would be a great help.
Thanks for reaching out. If you have questions or would like to request a video, please consider supporting the channel via Patreon at www.patreon.com/christopherwlum. I interact personally with Patrons at all levels. Thanks for watching!
AE511: Trying to wrap my head around how these different methods fit together. Seems like PID is most applicable in SISO, and FSFB is applicable to MIMO where you want the response to go to 0? Is it true that the response has to go to 0 with FSSB?
In the current formulation it is setup to return the system to the origin. That being said, this is the basis for other control schemes that use this and modify it so it can track a non-zero signal.
Thank you professor. Really enjoy it. Just wonder if C is not full feedabck (matrix C is not identity), but with A the system has observability, meaning one can estime x with y, can we still use full state feedback control here?
Hi Sken, Thank you again for your support of the channel. Given your support and interest in the topic, I'm happy to answer as best as I can. You bring up a very common problem, specifically in many cases you do not have full state measurement and your C matrix is not the identify matrix. However, if the system is observable, you can build a state estimator to estimate the state vector (I'm currently working on putting this video together). If the system is controllable (see my video at th-cam.com/video/oQDi3Giv-DI/w-d-xo.html) then you can apply the Separation Principle (en.wikipedia.org/wiki/Separation_principle) to use the estimated state vector as the input to your full state controller. I hope this is helpful, please let me know how it goes. I'll try to keep an eye out for your future comments and be sure to respond but sometimes TH-cam comments get lost due to the sheer volume of comments that the channel receives. I'm much more responsive on Patreon as this is a filtered list of interested parties. Thanks for watching and for supporting the channel!

[AE 511] The open loop system is one without the K gain added in, it is simply the state space representation where you plug in u and get out x_dot?
Close, the open loop system has u as input and y as output. In the case where you have full state output then y = x.
AE511: Trying to wrap my head around how these different methods fit together. Seems like PID is most applicable in SISO, and FSFB is applicable to MIMO where you want the response to go to 0? Is it true that the response has to go to 0 with FSSB?

Thank you for your lecture. I tried to run the second example(Non controllable) But it seems that my Matlab shows the rank=2 which means that the plant is controllable. Could you please check it. Best regards.
AA=[0 3;2 4]
BB=[0.5811;1]
rank(ctrb(AA,BB))
ans=2
is it possible?
