Fault Accommodation for near Space Hypersonic Vehicle with Actuator Fault
Based on fuzzy control and sliding mode observer technique, a fault accommodation strategy is proposed for near space hypersonic vehicle (NSHV) with actuator fault in this study. Firstly, the Takagi-Sugeno (T-S) fuzzy model is implemented to represent the NSHV nonlinear dynamics, and a bank of sliding mode observers are designed for the established T-S model, which are used to generate the resi...
متن کاملSmart Reconfigurable Fault-Tolerant Flight Control against Actuator Failures
In this study, active fault tolerant flight control technique with actuation reconfiguration is proposed. For this purpose two-stage Kalman filter (TSKF) is designed to identify the control distribution matrix elements corresponding to the faulty actuator, and a control reconfiguration action is taken to keep the performance of the impaired aircraft same as that of the unimpaired aircraft. Thus...
متن کاملApplied Actuator Fault Accommodation in Flight Control Systems Using Fault Reconstruction Based FDD and SMC Reconfiguration
Historically, actuators’ redundancy was used to deal with faults occurring suddenly in flight systems. This technique was generally expensive, time consuming and involves increased weight and space in the system. Therefore, nowadays, the on-line fault diagnosis of actuators and accommodation plays a major role in the design of avionic systems. These approaches, known as Fault Tolerant Flight Co...
متن کاملDirect neural control of hypersonic flight vehicles with prediction model in discrete time
In this paper, the direct adaptive neural controller is investigated for the longitudinal dynamics of a generic hypersonic flight vehicle (HFV). The objective of the controller is to make the altitude and velocity to follow a given desired trajectory in the presence of aerodynamic uncertainties. Based on the functional decomposition, the adaptive discrete-time nonlinear controllers are develope...
متن کاملOptimal nonlinear control of flight faults in manned aircrafts in the presence of fault and failure of control actuato
Control actuators' faults are among the major reasons to lose aircraft control while flights. The plane dynamics is severely dependent upon faults and errors in flight control systems and if the reformed control order is not issued by the fault tolerant controller there would be unpleasant outcomes such as inconsistency and the reduction of system performance and some dreadful aerial accide...
