In this thesis the integrated design of fault diagnosis (FD) for systems with both deterministic and stochastic disturbances is systematically presented. The integration in this contribution has two aspects. The first is integration of residual generator and residual evoluator. The second is integration of well-developed optimal deterministic FD and stochastic FD algorithms. With the twofold integrated design, optimal fault detection performance can be achieved. Many vehicle lateral dynamic control system, such as ESP systems, have recently been developed and widely equipped. It is of great significance to prevent these systems from wrong decisions caused by faulty sensors or actuators. The proposed integrated FD algorithms have been succsessfully applied to design FD systems to detect and isolate faults of vehicle lateral dynamic control systems. The design, test and evaluation of four FD systems are demonstrated, and the test and evaluation results based on both simulation data and real data sampled from more than 600 driving maneuvrs are given in detail.
