The two most significant contributions of this work are: 1) the demonstration of a fault adaptive control system applicable to higher order systems, and 2) a new methodology for designing BJ filters for high order systems, and systems with feed-through dynamics (i.e. output is a function of input).

The results provide a benchmark for the design of detection filters for use in fault-tolerant active vibration control.

Abstract

The objective of this work is to demonstrate a fault-tolerant vibration control system applicable in higher order systems. System failures are detected and isolated by Beard-Jones (BJ) filters. When such a failure is detected, the Fault Detection and Isolation (FDI) filter output is supplied to a hybrid automaton, which switches the system to a new controller that is specifically designed for the faulty system condition. The closed loop system, therefore, maintains optimal performance and stability under failure conditions. The two most significant contributions of this work are: 1) the demonstration of a fault adaptive control system applicable to higher order systems, and 2) a new methodology for designing BJ filters for high order systems, and systems with feed-through dynamics (i.e. output is a function of input). The capabilities of such a system are demonstrated through simulations based on analytical and experimentally obtained system models. The results provide a benchmark for the design of detection filters for use in fault-tolerant active vibration control.
