Abstract EN
In this work, a new integrated fault detection and control (IFDC) method is presented for single-input/single-output systems (SISOs).
The idea is centered on comparing the closed-loop output between the faulty system and fault-free one to schedule/switch the feedback control once the fault occurs.
The problem addressed in this work is the output disturbance rejection.
The set of feedback controllers are designed using quantitative feedback theory (QFT) for fault-free and faulty systems.
In the context of QFT-based IFDC, the proposed active approach is novel, simple, and easy to implement from an engineering point of view.
The efficiency of the proposed method is assessed on a flexible smart structure system featuring a piezoelectric actuator.
The actuator and sensor faults considered are the multiplicative type with both fixed and time-varying magnitudes.
In the fixed magnitude fault case, the actuator/sensor output delivering capability is reduced by 50% (multiplying a factor of 0.5 to its actual output), while in the time-varying magnitude case, it becomes 60% to 50% for a particular time interval.
In both cases, the proposed control method identifies the fault and activates the required controller to satisfy the specification with less control effort as opposed to the passive QFT design featured by faulty system design alone.
