Accelerated Landweber iteration based control allocation for fault tolerant control of reusable launch vehicle
文献摘要:
This paper presents a novel Fault Tolerant Control (FTC) scheme based on accelerated Landweber iteration and redistribution mechanism for a horizontal takeoff horizontal landing reu-sable launch vehicle (RLV).First,an adaptive law based on fixed-time non-singular fast terminal sliding mode control (NFTSMC),which focuses on the attitude tracking controller design for RLV in the presence of model couplings,parameter uncertainties and external disturbances,is pro-posed to produce virtual control command.On this basis,a novel Control Allocation (CA) based on accelerated Landwber iteration is presented to realize proportional allocation of virtual control command among the actuators according to the effective gain as well as the distance from the cur-rent position of actuator to corresponding saturation limit.Meanwhile a novel redistribution mech-anism is introduced to redistribute oversaturated command among healthy actuators (non-faulty or redundant).The proposed method can be applied to a real-time FTC system so that the controller reconfiguring is not required in case of actuator faults.Finally,the effectiveness of the proposed method is demonstrated by numerical simulations.
