For a 3rd order system, can I use 2nd order approximation (granted dominant pole is ≈5 Tau away from third pole), when designing a Lead or Lag compensator?
Can this OLTF = K/{s(0.1s+1)(s+1)} be approximated to 10K/{s(s+1) which ultimately gives CLTF=10K/{s(s+1)+ K} ? and then design Lead or lag network based on the performance specifications (which are given)
OLTF - Open Loop Transfer Function
CLTF - Closed Loop Transfer Function
