In order to effectively solve the risk of safety on power window, this study introduces the LMI-based
method of designing robust fault detection H∞ filter for anti-pinch window control system. For detecting the
pinched condition, the pinch torque is considered as a fault to design a residual generator. By comparing the
residual signal with the pre-designed threshold, the occurrence of pinch can be detected. The main contribution
consisted of the formulation of the multi-objective optimization H∞ and H- problem as H∞ optimization problem
by using the residual error instead of residual. The solution of the optimization problem is solved via LMI
technique. Based on MATLAB, the results show that the algorithm can detect the fault after it occurs 70 ms.
In addition, simulation results show that the proposed algorithm has high sensitivity to fault and strong
robustness to uncertainties.
