Fuzzy Attitude Tracking Control for Mars Entry Vehicles with External Disturbance
In this paper,a fuzzy tracking controller is designed for Mars entry vehicles during the entry phase in consideration of external disturbance.The original nonlinear attitude dynamics is divided into two subsystems based on the concept of time-scale decomposition.Dynamic inversion method is employed for the slow kinematic subsystem to give the angular velocity command by taking the attitude command as its input,which is generated by the guidance system of the entry vehicle.The T-S fuzzy model based control method is applied for the fast kinetic subsystem by taking angular velocity command as its input to derive the desired control torques in the presence of external disturbance.Finally,the simulation results on the Mars entry attitude tracking control are given to demonstrate the effectiveness of the developed method.
