摘要
Abstract
To address the issue of weak disturbance rejection and poor control accuracy in two-dimensional trajectory correction fuze-caused by the axial friction torque and the external aerodynamic disturbances during projectile flight-this study proposed a roll angle control method based on a fixed-time sliding mode control.This method ensured that the system converged within a fixed time,independent of its initial state.The stability of the designed control system was analyzed by using some relevant theories of the fixed-time convergence.Comparative numerical simulations with existing algorithms demonstrate that the proposed fixed-time control method enables both the roll angle and the angular velocity of the fuze to respond rapidly and accurately within a prescribed time.It also improves the system's control precision,response speed,and robustness.关键词
