What is causing this long tail in the transient reponse?

I have a fifth order transfer function for which I designed a controller using pole-zero cancellation technique on a root locus. I am targeting \$<5%\$ overshoot and \$<2s\$ settling time. Currently, the overshoot criteria are satisfied. Note I know…

Is it possible to simulate entire circuit designs before physically building the circuit?

I have spent a lot of time the past 3-4 months creating / improving my first circuit design which is a bldc motor driver circuit. I finally have a prototype which I think will work: Before I physically build this circuit I want to know whether or…

Need help with simulation of three-phase rectifier with hysteresis controller

I am attempting to design a closed loop three-phase rectifier with hysteresis control using MATLAB simulink. The outer loop compares output DC voltage with reference voltage, given to a PI controller and the output of the PI controller is multiplied…

How does a Delta-Sigma DAC work?

I have looked at how the Sigma-Delta ADC works and I understand it. However, it seems to me that there is not a lot of literature about the Sigma-Delta DAC. I want to build a model of it in Simulink. Can someone explain to me how it works?

What is wrong with my Simulink model of a first order Delta Sigma Modulator?

I'm trying to design a Delta-Sigma Modulator for frequency synthesizer applications and am (just right now) figuring out how to properly configure a first order DSM in Simulink. I've made a few small variations that I've seen (with the unit delay in…

SIMULINK: The spectrum of the modulated signal remains unchanged despite modification of the modulation index

I try to implement a frequency modulator. From what I know, the more I vary the modulation index (which is set by the gain block here,) the more the spectral lines should increase in number. When I increase the modulation index, the spectrum of my…

Truth table with logical gates for a traffic light

I want to create this truth table: So I tried this but I was not able to get the last row, which is: While a =1 and b =1 ,yellow = 1 red = 0 and green = 0. This is my design for it, but I could not make the last row. Does anyone have a sample…

Equations governing the impedance of a generalised constant-phase element in the time domain?

I apologize in advance for the large wall of text, but I feel like to properly ask this question, some background information is in order. I've been recently working on modelling the impedance of a circuit using the Mathworks SIMULINK/SIMSCAPE…
