This lecture covers the differences between open and closed loop systems in control systems. It begins with a review of open loop systems and their limitations, such as inability to handle disturbances. The lecture then introduces closed loop systems, which use feedback to maintain desired outputs and improve accuracy. Examples like air conditioners and geezers illustrate closed loop systems. A comparison highlights the reliability and complexity differences between the two systems. The lecture concludes with a preview of upcoming topics, including Laplace transforms.
