Simulação e Controlo de Drones (IST)

Simulação e Controlo de Drones (IST)

Este curso assenta na análise do funcionamento de drones multirotores e das partes que o constituem. Este curso tem como propósitos analisar o funcionamento de drones multirotores e das partes que o constituem, saber como desenvolver um simulador para analisar o seu comportamento e projetar soluções para o seu controlo automático.

A utilização de drones tem vindo a ser generalizada dada a sua larga gama de aplicações, nomeadamente no domínio civil. Estes são habitualmente utilizados para executar tarefas difíceis, monótonas ou perigosas para o ser humano, como é o caso da monitorização ambiental ou de locais de desastre, da aquisição de imagem com fim multimédia ou da fertilização de campos agrícolas. Por outro lado, podem ser utilizados apenas para fins recreativos.
No final do curso, os(as) participantes poderão:

  • Perceber o modo de funcionamento de drones multirotores;
  • Saber modelar os vários elementos do drone (atuadores, sensores e equações de movimento);
  • Desenvolver um simulador em Scilab/Xcos (ou Matlab/Simulink) para reproduzir e analisar o comportamento do drone;
  • Desenvolver soluções lineares para o controlo automático do drone, e implementar e validar as mesmas no simulador desenvolvido.

No curso serão abordados os seguintes assuntos relativos a um quadri-rotor:

  • Modelação: princípio físico, componentes, representação do sistema em espaço de estados e diagrama de blocos;
  • Simulação: implementação do sistema em anel aberto (atuação e equações do movimento) e dos controladores projetados em ambiente de simulação;
  • Análise: linearização, subsistemas de atuação e movimento, análise de estabilidade;
  • Controlo: estabilização do eixo vertical, angular e em translação, guiamento por pontos de passagem.

The use of drones has been widespread given its wide range of applications, namely in the civil domain. These are usually used to perform difficult, monotonous, or dangerous tasks for humans, such as environmental or disaster sites monitoring, image acquisition for multimedia purposes or the fertilization of agricultural fields. On the other hand, they can be used for recreational purposes only.
At the end of the course, participants will be able to:

  • Understand how multirotor drones work;
  • Know how to model the various elements of the drone (actuators, sensors, and equations of movement);
  • Develop a simulator in Scilab / Xcos (or Matlab / Simulink) to reproduce and analyze the drone's behavior;
  • Apply linear solutions in the automatic control of the drone, through its implementation and validation in the developed simulator.

The course will cover the following subjects related to a quadrotor:

  • Modeling: physical principle, components, representation of the system in state space and block diagram;
  • Simulation: implementation of the open-loop system (actuation and equations of motion) and the controllers designed in a simulation environment;
  • Analysis: linearization, actuation and movement subsystems, stability analysis;
  • Control: stabilization of the vertical movement, angular and translational motions, guidance by waypoints.

Modeling Time Series and Sequential Data (Coursera)

In this course you learn to build, refine, extrapolate, and, in some cases, interpret models designed for a single, sequential series. There are three modeling approaches presented. The traditional, Box-Jenkins approach for modeling time series is covered in the first part of the course. This presentation moves students from models for stationary data, or ARMA, to models for trend and seasonality, ARIMA, and concludes with information about specifying transfer function components in an ARIMAX, or time series regression, model. A Bayesian approach to modeling time series is considered next.

Applied Text Mining in Python (Coursera)

This course will introduce the learner to text mining and text manipulation basics. The course begins with an understanding of how text is handled by python, the structure of text both to the machine and to humans, and an overview of the nltk framework for manipulating text. The second week focuses on common manipulation needs, including regular expressions (searching for text), cleaning text, and preparing text for use by machine learning processes. The third week will apply basic natural language processing methods to text, and demonstrate how text classification is accomplished. The final week will explore more advanced methods for detecting the topics in documents and grouping them by similarity (topic modelling).

This is Course #2 in the Modeling and Control of Power Electronics course sequence. The course is focused on techniques of design-oriented analysis that allow you to quickly gain insights into models of switching power converters and to translate these insights into practical converter designs. The design-oriented techniques covered are the Extra Element Theorem and the N-Extra Element Theorem (N-EET). Through practical examples, it is shown how the EET can be used to simplify circuit analysis, to examine the effects of initially unmodeled components, and to design damping of converters such as SEPIC and Cuk to achieve high-performance closed-loop controls.
