对于具有未知过程扰动的状态空间系统，设计了一种鲁棒状态空间观测器，同时估计系统状态、故障的三阶导数和故障信号。只要所考虑的故障信号的有限次导数有界，就可以允许其无界。最后给出了一个数值例子来说明设计过程。汽车横向动力学系统对汽车的操纵性、稳定性和行驶安全性起着重要的作用。最后以汽车横向动力学系统的真实的数据为例，验证了该方法的有效性。版权所有（c）2006约翰威利父子有限公司。
For state-space systems with unknown process disturbances, a robust state-space observer is designed to simultaneously estimate the system state, the finitely times derivatives of the fault, and the fault signal. The considered fault signal can be allowed to be unbounded provided its finitely times derivative is bounded. A numerical example is given to illustrate the design procedure. Vehicle lateral dynamic system plays an important role in tile vehicle manoeuverability, stability and driving safety. An application example with the real data for the vehicle lateral dynamic system is finally provided to demonstrate the efficiency of the present estimation technique.
