Abstract: In the optimal control design for vehicular propulsion systems, the objective function describing the design objectives (fuel economy, driveability, comfort, emissions, battery operation, battery aging, etc.) plays an important role in defining the optimal solution. However, the definition of the objective function is not often analysed explicitly and thoroughly. In this study, a method of objectively analysing and evaluating the objective function is introduced. The method uses the singular value decomposition (SVD) technique to analyse the correlations among the design objectives and investigate their sensitivity to an optimal control algorithm. Accordingly, the dependent design objective(s) will be omitted such that the objective function can be simplified. This will reduce the complexity of the control design.
