Design of minimal and tolerant sensor networks for observability of vehicle active suspension

Due to the importance of sensors in allowing observability and in increasing redundancy and reliability, instrumentation is a crucial phase during plant design. In this brief, it is shown how to design a minimal and a tolerant sensor networks for the observability of vehicle active suspension. The system consists of a full vehicle model and actuator dynamics. Due to its complexity, the system is decomposed into five interconnected subsystems. This decomposition helps in treating each subsystem separately and allows the use of reduced order observers rather than one observer for the whole system.
