Introduction

The objective of this module is to use the Embedded Target for the C2000, and the Digital Motor Control Library (DMClib) to control a Permanent Magnet Synchronous Motor (PMSM) with an encoder using the Field Oriented Control Technique.

System overview

The following figure shows the complete application that we will implement step by step during the laboratory.

Variables description

ias = Phase-a stator current ibs = Phase-b stator currentias = Stationary a-axis stator current ibs = Stationary b-axis stator currentids = Synchronously rotating d-axis stator current iqs = Synchronously rotating q-axis stator currentvas = Stationary a-axis stator voltage vbs = Stationary b-axis stator voltagevds = Synchronously rotating d-axis stator voltage vqs = Synchronously rotating q-axis stator voltagevdc = DC-bus voltage qlr = Rotor flux angleqm = Mechanical angle dir = Rotor directionwr = Rotor speed Ta = Phase-a duty cycle ratio of PWM signalTb = Phase-b duty cycle ratio of PWM signal Tc = Phase-c duty cycle ratio of PWM signal

Simulation

The simulation process will be based on a simulation model for the PMS Motor.

Permanent Magnet Synchronous Motor (PMSM) Simulink Model

Based on this model, the simulation will comprise five steps as follows:

  1. Implementing the Forward Loop – Space Vector Generation
  2. Running the PMSM in open loop
  3. Closing the current loop
  4. The speed measurement-Encoder
  5. The Speed Closed Loop

Space vector generation

The diagram below highlights the modules used in the first step. This first incremental step confirms operation of peripheral and target independent modules on forward control path and the code framework.

Space Vector Generation

At this very first stage the goal is to generate a saw–tooth waveform with a varying frequency. This waveform is an emulation of the rotor angle, which is then passed into the Park transformation allowing us to check the correct computation of the Space Vector PWM needed for the Field Oriented Control.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.

what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
