The discussion focuses on the identification of conditions for lag and lead compensators in control systems. For a lag compensator, the pole (P1) is closer to the origin than the zero (Z1), leading to the conclusion that the magnitude of P1 is less than that of Z1. Conversely, for a lead compensator, the zero (Z2) is closer to the origin than the pole (P2), resulting in Z2 having a greater magnitude than P2. The confusion arises from misinterpreting the relationships between poles and zeros, which is clarified through examples involving specific values.
PREREQUISITESControl system engineers, students studying feedback control theory, and anyone involved in designing or analyzing compensators in engineering applications.
You are looking at the concept correctly, but you have one detail wrong. I am going to pose a question, hopefully this helps you get the right answer.x+3 = 0jaus tail said:
Actually for lead compensator the value of S in numerator has to be such that it is near to origin . Now s= -z ,so for value of s to be near to origin, z has to be of smaller magnitude as it has negative sign...similarly you can understand for lag compensator .jaus tail said:
