A unified framework for detection, isolation and compensation of actuator faults in uncertain particulate processes

Improved infinite horizon LQ tracking control for injection molding process against partial actuator failures

“…(11)(12)(13)(14)(15)(16)(17)(18), it is without difficulty to see that the uncertain process described by Eq. (4) is related to the nominal process model described by Eq.…”

“…A particular 2D Fornasini-Marchsini model based iterative learning controller was proposed by Wang, et al [13] for batch processes with actuator faults. In [14], unified robust detection, isolation and compensation for actuator faults are proposed. Wang, et al [15,16] shows that by assuming that the process delay is within a pre-described range, the FTC for such processes can be designed through robust iterative learning control (ILC) or guaranteed cost performance control using linear matrix inequality (LMI).…”

Fault Detection and Accommodation in Particulate Processes with Sampled and Delayed Measurements

“…8 These results were generalized to address the problems of fault isolation and robustness against model uncertainty. 9 Various implementation issues arise in the design of any fault-tolerant control system. These include measurement sampling and delays as well as the possibility of component faults.…”

“…An effort to address these problems was initiated where a methodology for the detection and handling of control actuator faults in particulate processes was developed based on low-order models that capture the dominant process dynamics . These results were generalized to address the problems of fault isolation and robustness against model uncertainty …”

Modeling and fault tolerant control of an electro-hydraulic actuator

“…Subsequently, with the development of smart machines and systems, safe operations and diagnosis of the malfunctions with desirable performances are becoming important aspects with time. Therefore, researchers have been showing interests to develop fault diagnosis algorithm (FDA) in various applications in recent years [5][6][7][8][9]. In parallel, by adopting control laws with the FDA, one can realize the FTC for any system.…”
