Abstract

In this paper, a full vehicle active suspension system is considered with the dynamics of the four force actuators. Being a large-scale and complex nonlinear system, it is physically decomposed into five interconnected subsystems. For each subsystem, a local controller is designed. Each control module is decomposed into functional submodules. In a higher level, a global module is designed to supervise all the submodules. In parallel to this hierarchical structure of control, a fault diagnosis structure is constructed. A local diagnosis module is designed for each subsystem to detect and isolate sensor faults. The local modules are monitored by a global module. Simulation is done to illustrate the system control, diagnosis, and fault tolerance.
