Abstract:

An adaptive sliding mode finite-time control method based on the generalized super-twisting algorithm is proposed to solve the attitude control problem of parallel carrier in the ascent phase affected by model uncertainty and external disturbance. Firstly, the attitude tracking control problem is transformed into the stabilization problem of tracking error system, and the control-oriented control model is established. Secondly, the single input single output (SISO) fixed-time generalized super-twisting algorithm is extended to multiple input multiple output (MIMO) coupled nonlinear systems. Based on the algorithm, a fixed-time state observer and an adaptive sliding mode finite-time controller are designed. The finite-time stability of the closed-loop system is proved based on the Lyapunov stability theory. Finally, compared with the traditional proportional and differential (PD) controller, the simulation results show that the proposed method has better control accuracy and robustness.

Key words: carrier, adaptive sliding mode control, finite-time control, generalized super-twisting algorithm
