“…First, the results in References to are established based on static redundancy, that is, the backup actuators (the redundant components) are operated in parallel even in the absence of failures. Such a principle, however, leads to long‐term wear‐and‐tear of the standby components . On the other hand, if identical components are utilized, one may be faced with the risk that all components suffer from a fault synchronously, caused by the same adverse condition, for example, shock, loss of power supply, and over‐temperature .…”

“…Motivated by the above discussion, this article devotes to develop a structurally simple and computationally inexpensive active FTC strategy for a class of nonlinear systems modeled in strict‐feedback form against actuator failures. Different from the related literature, it is permitted in this study that except for the known signs of the multiplicative nonlinearities, no preliminary knowledge of system nonlinear functions is requested, unlike the parametric uncertain form assumed in References , and ; the backup actuator is put in operation if and only if a failure happens, in contrast to the static redundancy studied in References to ; the goal is to maintain the predefined postfailure transient performance of output tracking, instead of uniform ultimate boundedness …”

Summary This article studies the fault‐tolerant control problem for unknown nonlinear strict‐feedback systems subject to actuator failures yet with dynamic redundancies. The prescribed performance control methodology is newly combined with a modification‐based supervisory switching strategy to solve the problem. To implement failure detection, the performance function is properly modified to synthesize a monitoring function to supervise the behavior of an error variable. Once a failure is detected, the current actuator is shut down and the backup actuator is switched in to execute the reconfigured control command. Compared with the existing results, (1) the postfailure and postswitching tracking performance is improved, other than uniform ultimate boundedness and (2) the dependence on extra robust control schemes (eg, adaptive or approximating structures) to deal with model uncertainties or the need to compute analytic derivatives of virtual control signals in the backstepping design is eliminated.

The aim of the paper is to present a supervisory decentralized architecture for the design and development of reconfigurable and fault-tolerant control systems in road vehicles. The performance specifications are guaranteed by the local controllers, while the coordination of these components is provided by the supervisor. Since monitoring components and the FDI filters provide the supervisor with information about the various vehicle maneuvers and the different fault operations, it is able to make decisions about the necessary interventions into the vehicle motions and guarantee the reconfigurable and fault-tolerant operation of the vehicle. The design of the proposed reconfigurable and fault-tolerant control is based on an LPV method that uses monitored scheduling variables during the operation of the vehicle.

Fault detection and diagnosis strategy based on AMT (Automatic Mechanical Transmission) system trajectory is studied. Hybrid automata is used to build healthy AMT system model. Then fault definition of AMT system is analyzed from the point of system trajectory and fault diagnosability of AMT hybrid system is studied based on AMT system's fault model and fault threshold function. According to AMT system model trajectories and control cycle, AMT hybrid system's behavior is analyzed and classified into three types: steady-state system behavior, discrete event trigger behavior and physical system response behavior. At last AMT system's fault detection and diagnosis strategy is proposed based on behavior types. The fault diagnosis strategy with the diagnostic algorithm is transplanted to the real car platform and a large number of vehicle mileage prove the strategy's correctness and real-time.
