Mixed H2/h∞ Approach to Detect Fault in Parallel Hybrid Electric Vehicle

In this paper a parallel Hybrid Electric Vehicle (HEV) is simulated based on the faulty condition. A dynamic output feedback robust Fault detection technique is used to evaluate the faulty condition when the missoperation cause that the output torque of parallel HEV, has been disturbed. This paper presents the fault detection method based on the mixed H2/H∞ approach, if the measuring signals are faulty. The simulation are based on the systems state space Model and then transferring it to Linear Matrix Inequality (LMI) to obtain the sub-optimal problem solution.
