Scilab Courses

rasppi logo

Scilab is an open source, cross-platform numerical computational package and a high-level, numerically oriented programming language. It can be used for signal and image processing, statistical analysis, Internet of Things, data mining, etc. In Trity Technologies we have developed more than 20 courses based on Scilab since last few years.

Raspberry Pi Courses

rasppi logo

The Raspberry Pi is a series of credit card–sized single-board computers developed in the United Kingdom by the Raspberry Pi Foundation with the intent to promote the teaching of basic computer science in schools and developing countries. Our very first Raspberry Pi Training is the aplication in IoT, and we are extending the training into other fields from time to time.

E4Coder - Automatic Code Generation

e4coder logo

E4Coder is a set of tools that can be used to simulate control algorithms and to generate code for embedded microcontrollers running with or without a realtime operating system. Our course focus on using the block diagram for algorithms development and the codes would be automatically generated and downloaded into the embedded boards such as Arduino Uno. A mobile robot application would be used for the training for practical hands-on.

Course Synopsis

wavarduinosignal

The problem of state estimation concerns the task of estimating the state of a process while only having access to the noisy measurements from that process. It is a very ubiquitous problem setting, encountered in almost every discipline within science and engineering. The most commonly used type of state estimator is the Kalman filter. The Kalman filter, named after Rudolf E. Kalman, is an optimal estimator for linear systems, but unfortunately very few systems in real world are linear. A common approach to overcome this problem is to linearize the system before using the Kalman filter, resulting in the extended Kalman filter. This linearization, however, is not without its problems. The development of better estimation algorithms for nonlinear systems has therefore attracted a great deal of interest in the research community, because improvements here will undoubtedly have great impact in a wide range of engineering fields.
 
This course is conducted in a workshop-like manner, with a balance mix of theory and hands-on coding and simulation in Scilab. Extensive exercises are provided throughout the course to cover every angle of algorithm design and implementation using Scilab. We have enhanced the training to include few soft real-time examples to make the course more interesting!
 

Course Methodology

image fork
The course begins with an overview of the estimation problem, and a review on the basic concepts in state estimation. The Kalman filter and its variants are then introduced in turn, each offering improvement/enhancement over its predecessor. The derivation of the main algorithms are covered, but kept to a minimum, to enable better understanding and to provide insight on the conceptual ideas behind these algorithms. Application examples are provided at the end of each section to help reconcile theory with actual practice.

 

Course Objectives

mousetracking

This course is intended as a practical introduction to the Kalman filter and its variants. As such, there will be a series of hands-on exercises which are generally aimed to help translate the theoretical models to practical applications.

Who Must Attend

Scientists, mathematicians, engineers and programmers at all levels who work with or need to learn about Kalman filtering and/or state estimation. No background in either of these topics are, however, assumed. The detailed course material and many source code listings will be invaluable for both learning and reference.

Prerequisites

A basic knowledge of probability theory, signal processing and Scilab programming is necessary.

What you will learn

Basic theoretical concepts and principles of the Kalman filter and its variants

Scilab implementation of the estimation algorithms
