Control theory Definition and 63 Threads

Most books I looked for Control Systems seem to be written by Electrical Engineers. Is there a good book which is written from the point of view of a Mechanical Engineers?

Hi all I have majored in mechanical engineering and I have taken some basic control courses in the universities so I am wondering how to control the aileron on an air craft or fins on a rocket so as to get the path you want. example : you want to change the air craft path to move up 10...

I am preparing for my control theory exam, but I have come across that I am struggling. I have a third order system and its asking to me determine when a value of an adjustable parameter, K for when the system is critically stable. I just don't know what this corresponds two for a third order...

I looked at several books as well as internet sources, none of them explain how the controllability matrix is formed. Given the linear time invariant system x'(t)=Ax(t)+Bu(t) A is an nxn matrix, B is an nx1 matrix, (assuming single input) Then controllability matrix R is given by...

I'm an engineering major, and my school has a lab that works on control theory. I think I would like to work on this in grad school, but I don't know if I have the background to look into it yet? I found a free textbook on the subject from Rutgers...

In most systems there is some sort of damping, but is it possible to develop a controller that works efficiently in a system with no damping? For example, imagine tracking the position of a linear cart moving on a track with no friction. Would it be possible to design a controller to supply a...

I have a zero at the origin of my root locus plot. I understand that I need integral control to have zero steady-state error. I have 2 questions about this. 1. When I add integral control like this, Kp (1/(Ti*s)) where Ti is from Z-N first method and Kp=1, I get a pole at the origin. I...

Im trying to figure out how a certain example is working. in this example the function x = g - \frac{k}{m} \frac{(z-z0)^2}{(i-i0)^2} where g, k, m, z0, i0 are fixed values and z, i are variables The function above is written as x = f(i,z) ( \sqrt{g} (z-z0) - y (i-i0) ) where f(i,z) is a...

Is a control theory class usueful for someone who wants to do experimental physics in grad school?

In my control theory textbook, frequency response descriptions is one of three main areas of the subject (the others being Laplace transfer functions and state space representations). My questions are: What is the purpose with frequency response in control theory? Why are not transfer...

I'm taking a course in control theory, and have been wondering for a while what the benefits are when you describe a system based on the Laplace method with transfer functions, compared to when you use the state space representation method. In particular, when using the Laplace method you are...

Does anyone know control theory? I need to know whether it can be used to find inputs for a neural network in order to produce a desired output.

Hi, I'm an undergrad major in electrical engineering and physics; I am also minoring in mathematics. I am thinking of going into the field of control theory. I was wondering what branches of mathematics are particularly relevant to the field of control theory (I had a mathematics professor who...
