A sliding mode control law is presented for nearspace vehicle (NSV) with backlashlike hysteresis to eliminate the influence of the input hysteresis.Firstlythrough analysis of backlashlike hysteresisthe hysteresis was decomposed into a certain linear part and an uncertain nonlinear part with known upper limit.Thenthe sliding mode control law was designed by tracking the desired output trajectory to eliminate the influence of the hysteresis.And the stability of the system was proved by using Lyapunov method.Finallythe control law was applied to NSV attitude control.The sliding mode control law is presented for NSV with backlashlike hysteresis.Simulation results illustrate that the proposed control scheme can achieve effective performance.
