### MIMO static decoupling matrix

I am trying to implement a static decoupling matrix of a MIMO system in MATLAB Simulink. This static decoupling matrix is of size 2x2 with some complex numbers, and the control scheme used for ...

### How to define the curvature of a function in simulink

English is not my native language so be tolerent please, you can edit the question as you pleases. I have a model in simulink (matlab) where I have a function (for example $f(x)$ like in the image), ...

### FIR filter approximation using a continuous time dynamical system

How can you approximate a Finite Impulse Discrete filter (FIR) using a continuous time linear dynamical system? I am seeing this problem using Matlab, where the resulting continuous system (obtained ...

### On Simulink, fzero function is an unsupported MATLAB function, is there any alternative?

I need to use "fzero" (or any alternative) function on Simulink, but MATLAB says: "Code generation does not support anonymous functions.". Is there any way to use this function on Simulink? I do not ...

### Direction of rotation in matlab/simulink

I have a general question. In Simulink, say you have identified an axis for a revolute joint (x,y,z):(1,0,0) and you plot the angle. Is the normal convention the right hand rule? In this case positive ...

### Roll PID Control for quadcopter

I'm trying to implement with simulink a PD controller for my quadcopter. I use a simplified model, and for the roll case I have $I_x * \phi = L$, where L is the roll torque. So, the transfer ...

### How does MATLAB Simulink get such accurate ODE solution results?

I have a fixed-step model (0.001s) in Simulink in which a second order ODE is effectively being set up, a free spring-mass-damper system (m=2, c=0.3, k=1, x0=0, x_dot_0=4). I am studying the solvers ...
I have some trouble with a challenging fluid mechanics problem. The problem leads me to a non-linear ode 1st order. $0={\dot p_C}^2+\frac{k_1}{k_2 C}\dot p_C+\frac{p_C-p_0}{k_2C^2}$ My Idea was now ...
