This model simulates a three phase rectifier based on space vector pulse width modulation. Parameters can be adjusted from Model properties initial call back function.
The simulation for educational purposes shows the resulting rotating vector from the 3 by 120 degrees shifted sinusoidals in a phase plane.
random_band is the main program and it outputs a test signal which has a constant level. The instanatenous frequency varies randomly within the specified Nth octave band range.
The program outputs three plots: time record of the...
function y = getiq(x,freq)
this takes in the frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q - this is used when you have frequency X changing and the phase is cumulative - meaning it does not...

Sigmoid creates a Sigmoid function using parameters in PARAMS and the variable range.
V = SIGMOID(PARAMS,RANGE)
PARAMS: a 3-vector, the entries of which are (in this order):
2-D zero phase digital FIR filter using Hamming Window
It is a new block simulink signal library called the Phase Filter.The transfert function is F(p)=(1+T1p)/(1+T2p).Students can change parameters T1 and T2 time constants of filter.The phase filter in automatic control is for Corrector block and...
It simulates three phase simple PWM-180 degree conduction based inverter. Frequency and output voltage can be changed using slider gains block used.
The Code describes the way to modulate or demodulate a signal shift in its phase.

Mu-Tools based Multivariable System Identification
The Musysid folder contains some useful tools for :
- black box MIMO system identification
- state space system fitting from a given frequency response
The advantages of vector control provide variety of control choices in the PMSM drives. The simplest control strategy is the Zero d_axis current control (Constant Torque Operation) which is implemented in this model. The transient responses of...
This program converts the noise sidebands to power, adds in an estimate of the power for CW spurs, then calculates the jitter from this. It is not really exact, but it is simple and allows for an easy estimate of the jitter and phase noise without...
The model simulates single phase bridge rectifier with resistive and inductive load. simulation also demonstrate the role of free wheeling diode. Single phase pulse generator was developed to generate the pulses at required firing angle.
PITAN(NUM,DEN,W) plots the stability boundary locus L(KP,KI,W) in the (KP,KI)-plane for an LTI system with transfer function defined by its NUM, DEN coefficients and driven by a PI controller with transfer function, C(s)=kp+(ki/s). Frequency (W)...
