The block diagram is to represent a control system in diagram form. Working Diagram, Examples, PDF. We will start in Sections 4.2 and 4.3 with two systems that can be handled using only knowledge of differential equations. The above block diagram consists of two blocks having transfer functions G(s) and H(s). Sec-tion 4.2 deals with design of a cruise controller for a car. Reading Time: 4 minutes.
