Industrial Controllers - Why not adaptive control and robust control

This is a question I have thinked about under a very long time. What are industrial controllers? From research I found that PID is the most used in the industry. PID controllers are included in ...

Extended Kalman Filter in robotics - Worth it?

I wonder if Extended Kalman Filter(EKF) is used in robotics, or is only Kalman Filter(KF) used in robotics. Kalman Filter is included in Linear Quadratic Gaussian(LQG) controllers. But how would EKF ...

Should the kalmanfilter have disturbance as input?

This is a kalmanfilter As you can see, the process noise(disturbance) is not going to the kalmanfilter. But the state space model for the state feedback system is written as this: https://youtu.be/...

Why doesn't this kalmanfilter filter anything? Reduce disturbances and noises with LQG controller

I have a state space model which look like this: $$ \ \begin{bmatrix} \dot{x} \\ \\\dot{\tilde{x}} \end{bmatrix} =\begin{bmatrix} A - BL& BL \\ 0 & A-KC \end{bmatrix} \begin{bmatrix} x\\ \...

Can I write the seperation principle for LQG controllers in this state space form?

Look at this picture. This is the seperation principle diagram. It is an LQG controller which going to control the real life process. What I want to do, is to create a state space model for this ...
