Q-4: The following transfer function is not written in a standard form: 2(s + 0.5)e-5s G(S) = (3s + 1)(2s + 1)(s + 1) (a) Approximate G(s) as a FOPTD using Taylor series expansion. (b) Approximate G(s) as a FOPTD using Skegestad half rule. (c) Compare their accuracy using Simulink. (d) Find the G(s) if the time-delay term is replaced by 1/1 Pade approximation. Determine the gain, poles, and zeroes
