State estimation in HyperSonic Missiles
I'm curious, what would be the correct approach for state estimation for hypersonic Missiles?
Would it be exclusively GPS and IMU? Historically these are what was used, but I have also seen ground stations with radar or broadcast triangulation used…

Kalman filter for harmonic oscillator. State variable and Covariance matrix
I've coded a simple damped harmonic oscillator, controlled with a pid. Works fine.
I want to use this model to test a kalman filter. So i added a gaussian noise to the position and want to feed the noisy position to a kalman filter but im a little…

Does the frequency response assume the zero input response to be 0?
I'm a bit confused about the frequency response and the state of a system. Is it simply the ratio of the output of the zero state response to the input of the zero state response? Or does it include the zero input response? Any clarifications would…

IIR initial condition / state meaning
I am studying filters, in particular the Infinite Impulse Response ones.
I digged into theory and practice and I gain some decent knowledge on the topic. However, I can't really figure out or find good resurces about the so called "Initial…

Gradient descent applying chain rule in state space setup
Trying to perform system identification in the following state-space model
$$
\begin{bmatrix} x_{1}(n)\\ x_{2}(n) \\ x_{3}(n)\end{bmatrix}=\begin{bmatrix} a_{11} && a_{12} && a_{13} \\ a_{21} && a_{22} && a_{23} \\ a_{31} && a_{32} && a_{33}…
