SUMMARY

The discussion focuses on designing a lag compensator using Ogata's method, specifically addressing the calculation of the velocity constant Kv and the gain K. The user expresses confusion over the choice of Kv as 5 1/sec and the rationale behind the 40-degree phase margin requirement. Additionally, they seek guidance on applying these concepts to their open-loop transfer function.

PREREQUISITES
  • Understanding of control systems and compensator design
  • Familiarity with Ogata's "Modern Control Engineering" methodology
  • Knowledge of open-loop transfer functions
  • Basic concepts of phase margin and stability analysis
NEXT STEPS
  • Research the calculation of Kv in lag compensators using Ogata's method
  • Study the implications of phase margin on system stability
  • Learn how to derive gain K from an open-loop transfer function
  • Explore practical examples of lag compensator design in control systems
USEFUL FOR

Students and engineers involved in control systems design, particularly those working on lag compensators and seeking to understand Ogata's methodologies.

Hello Community,

for a School Projekt I must design a lag compensator according to Ogata. Unfortenutely I have some Problems. At first I must find a Value for Kv. I don't know why he use for Kv 5 1/sec in this example. He don't explain why he use 5 and why he use at least 40 degrees.

In the next step he calculate K with lim in this example.

How can i Use this Method for my open-loop transfer function and how can I determine that?
