Design of rocket artillery motion controller based on adaptive sliding mode control
Currently,rocket artillery systems present challenges due to their complex structure,gaps in the transmission system,and the inherent difficulty in accurately calculating friction.Additionally,changes in system mass and center of gravity occur during projectile launch,complicating the establishment of a precise dynamic model for the design of motion controllers.Consequently,traditional control algorithms based on models encounter difficulties in achieving satisfactory control performance.To address these challenges,this paper proposes an adaptive sliding mode control method based on fuzzy control.Under conditions including a fixed disturbance of 50 N·m and a 20％uncertainty,this method exhibits a maximum steady-state error of-2.38 × 10-3 rad.The results indicate that the fuzzy adaptive sliding mode control enhances the robustness of the control system,allowing it to more effectively adapt to changes and resist disturbances.Simulation results further validate the feasibility of this innovative control approach.
