IEEE TELLs

IEEE hosts a series of Tiny Electronic Learning Lectures (TELLs) where upperclassmen and graduate students demonstrate an interesting technology. TELLs are recorded and published online to benefit the Hopkins and Internet communities. Videos are published in MPEG-4 H.264 format. For best playback, use VLC Media Player or Quicktime.


Non-Linear Controls


Hassan Mohy-ud-Din presents an elementary introduction to State-Space Representations, Stability, Lyapunov functions, and Limit Cycles. The talk, largely applications based, revolves around the design and analysis of Non-Linear Control Systems with emphasis on the dynamics of the system.
