    How many sample is enough for System Identification

    Hi, I am working on speed control of a BLDC motor. Instead of an encoder, the motor driver provides a channel from which I can measure the rotational speed of the motor. I have tried various input signals to the BLDC - driver system and successfully measured the output speed which I then used in...

    Matlab step input to a MIMO system

    Thanks mate, I got it done but with lsim command, I have the same plot so result wise both methods are good I guess. I'll definitely try out ode45 for my BLDC simulation.

    Matlab step input to a MIMO system

    Hi I'm modeling a drone using the state space equations in the picture. Normally, the step(sys) command would, for MIMO systems, plot the step responses for each I/O channel. However, I would like to define my own input and have a step response of two channels (ft and ty) simultaneously, is ii...
