Dynamic Integral Sliding Mode For Launch Vehicle Attitude Control System

As it is known that launch vehicle is facing a very harsh environment during the fight process.The challenge of various perturbations and uncertainties has lead to many traditional control methods' failure to meet the requirements of attitude control system.Due to the main advantage of sliding mode control's robustness to the system uncertainties and disturbances in the so-called sliding mode,it has been widely used in engineering.In this paper,regarding particularly on chattering problem,the authors developed a novel dynamic integral sliding mode control scheme and the comparative simulation results carried out with traditional integral sliding mode demonstrates the superiority of the newly designed control law.
