Please consider the following closed-loop Multiple-Input Multiple-Output (MIMO) control system:
R₁(s) and R2(s) are the reference signals (or inputs),
•
G₁(s) (where i = 1,2,3,4,5) are the plant transfer functions,
•
C₁(s) and C2(s) are the responses (or system outputs),
•
All of them are in Laplace domain.

The natural gas consists primarily of CH4 with small quantities of several other light hydrocarbons and can be represented as C1.16H4.32 To achieve low emissions of oxides of nitrogen, the burner operates lean at equivalence ratio of 0.4. Assume complete combustion and answer the following questions. i) What is the operating air-fuel ratio (i.e. mass air/mass of fuel)? [6 marks] ii) What is the percent excess air in the combustion products? [3 marks] iii) What is the oxygen (O2) mole fraction in the combustion products? [6 marks]arrow_forward
