Direct Computation of the Performance Index for an Optimally Controlled Active Suspension with Preview Applied to a Half-Car Model
Abstract:A quadratic integral performance index is defined for a linear active preview–type suspension and a series of matrix expressions derived for its evaluation by means of MATLAB or some similar computer program in the case of a unit step input to the system. The computation, which is both fast and accurate compared to simulation, requires the solution of Lyapunov– and Riccati–type equations. Some examples of numerical computation are given and these show excellent agreement with published results. The conclusion features a useful computer program.
