摘　　要：研究了有突变故障采样数据(SD)系统的最优等价空间残差产生器的设计。针对用等价空间残差产生器进行SD系统故障检测时,检测结果的好坏与等价空间向量的选择密切相关,设计SD系统等价空间残差产生器的传统间接优化方法和直接优化方法均把扰动和故障看做是同一类型,导致最后设计的有突变故障SD系统残差产生器对扰动的鲁棒性差,无法对突变故障进行有效检测的情况,提出了一种设计最优等价空间残差产生器的新的混合优化方法。理论分析证明,用该方法设计的等价空间残差产生器的性能,要优于采用传统直接优化方法和间接优化方法设计的产生器,而且随着等价关系阶数s的增大,性能会进一步增强。仿真结果验证了该方法的有效性。The design of the parity-space residual generator for sampled-data （SD）systems with abrupt fauls was studied Based on the analysis of the current circumstances that when using a parity space residual generator to detect the abrupt faults in a 3D system, the detection result is closely related to the selection of parity-space vector and the fault and disturbance are considered as the same type by the traditional indirect optimization method and direct optimization method for design of parity space residual genecators, so the parity space residual generator designed with the two methods has the worse robustness to disturbance and can not effectively detect abrupt faults in SD systems, a novel hybrid optimization method was proposed for design of optimal parity-space residual generators. The theoretical analysis indicates that the performance of the parity space residual generator designed by using the proposed hybrid optimization method outperforms that of the generator designed with the indirect optimization method or the direct optimization method, and with the increase of the order of parity relation, the performance will be further improved. The effectiveness of the new method was verified by the simulation results .
