Feedback Control Systems Signal-flow Graphs Engr. Lancer Andre T. Mendoza PRESENTED BY
Back to Agenda 1. How do signal-flow graphs differ from block diagrams? 2. What are signal-flow graph algebra rules? 3. How do signal-flow diagrams be constructed? Essential Questions
Back to Agenda Signal Flow Graphs • A pictorial representation of the simultaneous equations describing a system. • Graphically displays the transmission of signals through the system. • Easier to draw and easier to manipulate than the block diagram.
Back to Agenda Signal Flow Graphs TRANSMISSION FUNCTION • Aij = a mathematical operator mapping Xj and Xi • Aij may be a constant, in which case Xi is a constant times Xj • If Xi and Xj are functions of s or z, Aij may be a transfer function Aij(s) or Aij(z) . Xi = AijXj
