About Control Systems Academy

Basic Info

This portal provides a number of interactive examples focused on control system theory. Crafted by researchers focused on controls of electromechanical systems, the intent is to help students and engineers "connect the dots" by showing the relationships between the frequency and time domains and to elucidate some of the more abstract control theory analysis and design concepts.

What is here?

1) A series of articles focused on control system theory are to be found here.
2) A web-based simulator suited to test out concepts right away without MatLab/Simulink installed on your machine.
3) Bode Plot Engine, a computing and plotting environment with combined symbolic and numerical inputs.
4) Many other articles focused on power electronics, motor control, and instrumentation.

This site is viewed complementary to other websites focused on control theory- because those do not have the interactive elements, which are deemed crucial to understanding the nuances of analysis and design techniques.

MatLab(©) Compatibility

Interactive demos are complemented by MatLab(©) code examples that allow the reader to readily port script to a standalone MatLab(©) application. All examples were extensively tested for 1:1 match with MatLab.
