The increased complexity in system and the growing need of advanced and complicated actuators and sensors towards higher level of automation and autonomy in different engineering applications render the engineering systems susceptible to faults, which may significantly degrade the control performance or even cause catastrophic accidents.Recently, fault detection and diagnosis (FDD) and fault-tolerant control (FTC) techniques have been widely used to diagnose and compensate for the actuator/sensor faults, respectively.However, the capabilities of the traditional FDD and FTC methods are significantly degraded when the actuator or sensor faults are encountered by the highly nonlinear engineering systems (such as unmanned aerial/ground/surface/underwater vehicles and high-speed trains) with various internal physical constraints and external disturbances.Therefore, combined with new developments on big-data, adaptive learning, intelligent control, etc., latest developments on the FDD and FTC techniques will be intensively pursued in this special section with six articles selected by the guest editors.
