I typed locus to watch black ops 3 locus sniper gameplay but i decided to watch this and...

I have no idea what this is😂😂👏👏🤔🤔

Some people were born to teach, you are one. Unfortunately most professors aren't

I took an entire semester of controls, and in your 11min video I finally understand lead compensator. Jeez. You're great.

[BrianBDouglas]

Thank you! I'm working on the lag design right now ... should be up by the weekend. Standby :)

[BrianBDouglas]

Great! It's impossible to cover all of the topics of classical controls in a single semester (and make sense of it all) so professors have to pick and choose what they think is important. Congrats on the A. It's sounds like you have a knack for control theory.

[chinmaychhatre]

Sir can you include more examples in your videos? i.e start with some transfer fuction.. then design lead compensator and then drawing toot locus of the same..
AS ALWAYS love your video.. :)

I honestly wish I had just watched all these videos instead of going to systems and controls lectures

[rahulshiv]

This 14min video gave me better intuition for lead compensators than the 100-page chapter in my textbook. Thank you so much!

[prateek-yp]

This 13 min video is equivalent to the whole semester dedicated to lead lag compensator

Thank you, seriously thank you! Now it's all about finding the proper way of inputting z and p values to not disturb the dominant poles and still have access to a proper response to the closed loop system....

[BrianBDouglas]

Hi LouAnn, A lead compensator can only add up to 90 degrees of phase (and that's only if the pole is way off to the left towards -inf). But realistically a lead compensator can really only add about 55 deg of phase due to restrictions in the size of the components needed to make it. Therefore, in order to get 90 deg of phase you'll need to add two lead compensators. Try designing one compensator to add 45 degrees of phase and then create a double pole and zero at that point.

you know what Brian, the entire class of my control course were watching your video for exam study last night.. you are awesome!! 

[zhuokaizhao]

Could you please share the way that you used to get the gain K??  Thanks!

[mkschreder]

Do you have a video on converting requirements to desired pole locations?

[luisgonzaloandrade]

At 9:50 when he is adding all the angles of the poles for the angle criterion, why doesn't he add the angle made by the complex conjugate pole. That would add an extra 90 deg making the total 315 deg instead of 225 deg. Please and thank you for the clarification.

[bbq]

so how do we determine the K after finding a good z and p?

[treyvives]

Is there a video where you found k using the magnitude criterion?

[jzvf_]

you have videos that are connected to each other, it would be nice if you would link them in the description. for example how to find K. I dont know which video to go get that information from

Man, you're saving me on this quarantine period on university. Many thanks, you do a great job!

[shalaiot]

Thank you! Your lectures brought me a great help in my understanding control system.
