Vehicle Dynamics Equation Identified by combined Invariant Subspace & Subspace Method

This paper includes two parts: The first part is the introduction of a system identification method called combined Invariant Subspace & Subspace Method (cISSIM) proposed recently. The other part is the utilization in the form of identifying vehicle dynamics model via numerical simulation. cISSIM takes multi-sine waveform as excitation signal, and outputs the states-space expression of a linear time invariant system. The method can work with slow-sampled data obtained from an error-in-variables system, which has a wide prospect in practical. The simulation provides empirical evidences about it. Some considerations in implementation are also provided.
