Fault Recovery of a UAV using MATLAB
I'm currently investigating fault recovery in a UAV using MATLAB.
I've been given several variables:
phi = the roll angle
psi = the yaw/heading angle
beta = the side slip
p = roll rate
r = yaw/...

How to model a double transfer function in Simulink?
I'm trying to model an actuator in Simulink based transfer functions previously derived.
One of functions is $$\omega_p=G_2(K_cG_1V_c-c)$$ where $$G_1=\frac{K_e}{\tau_es+1}$$ $$G_2=\frac{1}{c+...

How to find closed loop transfer function and use it to identify τ and k?
I have to answer a few questions on transfer functions using Matlab. The first question, which I solved without Matlab, gives a time response graph for an LR circuit, and asks me to find the first ...

effect of coupling in MIMO systems
I have a MIMO system with a 2x2 transfer matrix, for example consider:
$\begin{pmatrix}
\frac{2}{s+1} & \frac{1}{(s+1)(s+2)}\\
\frac{1}{(s+1)(s+2)}&\frac{2}{s+2}
\end{pmatrix}$
I would ...

How to find Performance assessment (IAE and ISE) of a PID Controlled system?
The Integral Absolute value Error (IAE) and the Integral Squared Error (ISE) is to be analysed.
A PID Controller is given as follows:
\begin{gather}
C(s)=K_p+K_i\frac{1}{s}+K_ds
\end{gather}
where $...

How to input amplitude on a second order transfer function?
I have some samples of readings from an accelerometer (unit: g) and I did a FFT (on MATLAB) on the vector generated from these samples to see its frequency spectrum. Then I have isolated the peaks and ...

What are the Singular Values of a dynamic system and how are they calculated in the *sigma* function in Matlab?
According to Matlab documentation:
sigma plots the singular values of the frequency response of a dynamic system.
bode creates a Bode plot of the frequency response of a dynamic system.
I am ...

calculate output $y(t)$ from $Y(z)$ having discrete closed loop model with sine input - residue method
I have closed loop - discrete model. This is how it looks in matlab:
I need to compute analitically output $y(t)$ (same as in the Matlab's scope) having $Y(z)$.
Where
$Y(z)=U(z)*G(z)$
Input is sine ...

Closed loop response of a discrete system
I have trasfer functions of a plant and a controller in laplace domain. I checked for the closed loop response by applying a step response. The system is found to be stable.
I checked the response ...

mass calculation from transfer function or bodeplot
I have a double mass rotary model. The two masses are connected by an axis which together acts as a spring damper system of the fourth order. The system is actuated by a motor and the angle of ...
