Question 2 Consider a chemical process problem that has the transfer functions as given below: 3 G Gm(s)=et 0.1s +1' G,(s)= (4.2s+1)(0.75 +1) (=(1+ 45) 0,6)=15/14.) 1.5(85+1) 1 4s Analyze the transfer function to determine the value of transmitter time delay, on for a gain margin of 3. If there was a modelling error in determining the process transfer function where the process gain should have been doubled from its original value, evaluate if system still maintain a stable response. Justify your answer. [25 Marks]
