This is Ray Phan's free video lecture page for lectures on Electrical & Computer Engineering and related topics. Videos will be placed on this website as I teach courses, or when I TA courses where it merits video capture. The courses that I have taught and are available online on my website so far are: - ELE 635 - Communication Systems: Winter 2009 - ELE 639 - Control Systems: Spring 2009, Spring 2010, Spring 2011 - MTH 820 - Image Analysis: Winter 2010, Winter 2011. Ray Phan is a Ph.D. candidate with the Department of Electrical and Computer Engineering at Ryerson University in Toronto, Ontario, Canada. He is currently a Vanier Canada Graduate Scholar, the most prestigious and highest valued Ph.D. scholarship to be awarded for Ph.D. study in Canada. For more information about myself, please see: http://www.ee.ryerson.ca/~rphan/RayCV.pdf
This covers the first half of Lab #1 for MTH 820: Image Analysis at Ryerson University for the Winter 2012 semester. The topics covered are some basic point/intensity transformations: gamma law, rudimentary object extraction, and how to extract bit-plane images, or performing intensity slicing transformations. To access the code and the notes I've made on my tablet PC, please go here: http://www.rnet.ryerson.ca/~rphan/mth820/w2012/lab2/
In this lab, a quick primer on how to do some basic input/output with images is shown: how to read images, how to save images, how to display images, how to access and modify pixels, and data types. To access the notes I created on my tablet, please go here: http://www.rnet.ryerson.ca/~rphan/mth820/w2012/lab1/
In this video, I go through a quick introduction on how to get Simulink up and running, and to help you learn the basics of how to create a system to simulate. I use the block diagram on Page #2 of the Lab #1 document for the Winter 2012 semester. This video serves as supplementary material to the slides that I've created for the Simulink tutorial during the first week of labs during the Winter 2012 semester. This simply increases your options in reviewing how to work Simulink - either by the ...
In this second part of the Final Exam Review for Spring 2011, I go through Lead and Lag compensator design. I solve two questions for Lead, and 1 question for Lag.
In this first part of the second half of the final exam review for ELE 639: Control Systems for the Spring 2011 semester at Ryerson University, I go through 3 detailed examples on sketching the Root Locus plot, and solving for the proportional again required to move a particular pole to a point on the Root Locus.
We begin our final exam review here for ELE 639: Control Systems for the Spring 2011 semester. In this portion, we go through Gain and Phase Margin definitions, determining second-order underdamped model parameters from open-loop bode plots, and analyzing stability from these plots.
Simply a continuation of Lecture #12 for ELE 639: Control Systems for the Spring 2011 semester.
This is Lecture #12 for ELE 639: Control Systems for the Spring 2011 semester at Ryerson University. A continuation of controller design in the frequency domain took place, where the analytical methods for lead and lag, and the simplified method for lag were covered. Due to time constraints, I did not cover Lead-Lag controllers. However, should you wish to study them, please consult Lecture #12 for the Spring 2010 semester, and scrub near to the end of the video.
In this next part, I go through a brief introduction in controller design in the frequency domain. I describe why studying this area is very important, and I talk about the first of three controllers commonly see in this area: The Lead Compensator. I go through the simplified method of designing this controller, as well as an example
This is Lecture #11 for ELE 639: Control Systems at Ryerson University for the Spring 2011 semester. In this lecture, we go through how to analytically calculate the Phase Margin of the second-order underdamped model, as well as determining the second-order underdamped model using the open-loop Bode Plot.
