Advanced Kalman Filter Theory and Practice

This intensive course is designed for engineers and scientists who need to deepen their understanding of the mathematical foundations of Kalman filtering and learn new practical techniques to build and maintain real world Kalman filters.

Prerequisites:An undergraduate degree in engineering, natural science (physics, chemistry, etc.) or mathematics. An advanced degree in one of these fields will make it easier to grasp a few of the concepts presented, but nothing in the course presupposes such advanced work. Some practical acquaintance and/or experience with applications of Kalman filters in real world situation will certainly enrich the learning experience in this course but, again, are not required.

To increase your understanding of Kalman filter theory and provide hands-on experience in solving practical problems associated with the design and construction of Kalman filters.

Course Style: This is an intensive, highly interactive seminar. The participants will not be mere passive spectators at a series of lectures. Class participants will have ample opportunity to exercise what they learn. The course is divided up into segments with each segment lasting approximately 2 hours. There are 4 segments each day. Each segment is 2 hours long and is structured as follows:

q       1-hour interactive presentation of new material

q       30-minute exercise session

q       15-minute exercise review period

q       15-minute break


  The 30-minute exercise session usually consists of two parts: an individual part (15 minutes) and a workgroup part (15 minutes). The student will have the opportuntity to work both alone and as part of a workgroup. The workgroups are arranged so that the level of skill and experience is balanced across workgroups.


 Sample content from Day 1, Segment 1, including the exercise session at the end, are provided here in a PDF file: Set Theory (PDF). (Note this segment is only about the half the length of other segments, because it is preceded by an introductory session on Day 1.)


Most of the segments also have Matlab m-files and/or Simulink models associated with them. For example, the segment on linear systems theory uses the following pair of files (among others): State Space Generation m-File and Generic State Space Model.


Course Content:

 

Stochastic dynamic systems (both linear and non-linear) play a central role in Kalman filter theory. Thus the course will provide a solid grounding in the mathematical concepts and techniques underlying such systems. Also, a brief introduction to Hilbert Space theory will be provided, since optimal estimation techniques such as the Kalman filter can be briefly characterized a orthogonal projection in Hilbert space. Many fields of modern science and engineering employ Hilbert Space concepts and techniques; for example, in engineering they play a key role in digital signal processing and in physics they are used in quantum mechanics. Hilbert Space is not as scary as it sounds. It is really only a generalization of 3-dimensional Euclidean space to an infinite number of dimensions. The concepts of inner product (aka dot product), orthogonality, norm (aka vector magnitude), and linear transformations are already familiar from 3-space. In addition to these more mathematical topics, useful practical techniques for identifying appropriate state models based on empirical input-output data will be taught. Hands-on problem solving using these techniques will help class participants acquire solid engineering tools.
