N2 - In this paper, the rapid attitude stabilization problem of guided spinning projectile (GSP) with uncertainties and disturbance is investigated. First, a coupled attitude dynamics model for GSP was developed as control plant with parameter uncertainties and external disturbance. Then a sliding mode based fixed-time trajectory linearization control method is presented with a novel fast fixed-time integral sliding mode (ISM). The ISM is singular-free and ensuring the settling time independent to the initial condition. Moreover, an adaptive sliding mode control (SMC) technique is then synthesized to alleviate SMC inherent chattering. The stability and fixed-time convergence of GSP states are rigorously proved. The numerical simulations are carried out to validate the efficient of proposed control scheme in attenuating system uncertainties.
