power_brushlessDCmotor
A three-phase motor rated 1 kW, 500 Vdc, 3000 rpm is fed by a six step voltage inverter. The inverter is a MOSFET bridge of the SimPowerSystems™ library. A speed regulator is used to control the DC bus voltage. The inverter gates signals are produced by decoding the Hall effect signlas of the motor. The three-phase output of the inverter are applied to the PMSM block s stator windings. The load torque applied to the machine s shaft is first set to 0 and steps to its nominal value (11 N.m) at t = 0.1 s.
Two control loops are used. The inner loop synchronises the inverter gates signals with the electromotive forces. The outer loop controls the motor s speed by varying the DC bus voltage.

OFDM-Sim-Using-Matlab
Orthogonal frequency division multiplexing (OFDM) is becoming the chosen
modulation technique for wireless communications. OFDM can provide large data
rates with sufficient robustness to radio channel impairments. Many research centers
in the world have specialized teams working in the optimization of OFDM for
countless applications. Here, at the Georgia Institute of Technology, one of such
teams is in Dr. M. A. Ingram’s Smart Antenna Research Laboratory (SARL), a part
of the Georgia Center for Advanced Telecommunications Technology (GCATT).
The purpose of this report is to provide Matlab code to simulate the basic processing
involved in the generation and reception of an OFDM signal in a physical
channel and to provide a description of each of the steps involved. For this purpose,
we shall use, as an example, one of the proposed OFDM signals of the Digital
Video Broadcasting (DVB) standard for the European terrestrial digital television
(DTV) service.
