Back to Agenda Closed Loop Transfer Function (CLTF) CLTF = Y s X s = G s 1 ± G s H(s) Where: U(s)= actuating (error) signal B(s) = feedback signal Note: For positive feedback, (-) For negative signal, (+)
Back to Agenda Open Loop Transfer Function (OLTF) OLTF = G s H(s) CLTF = G s 1 ± OLTF Where: U(s)= actuating (error) signal B(s) = feedback signal Note: For positive feedback, (-) For negative signal, (+)
Back to Agenda TYPES OF SYSTEM • Defined as the number of poles of the system • Designed for an Open Loop Transfer Function • Should be a Negative Unity Feedback System OLTF = G s H s Where, H s = 1 Thus,OLTF = G(s)
