Abstract :
In this paper, we study integrated guidance and control system considering the input saturation and state constraints for homing missiles. Command filters are exploited in the control design to deal with the state and actuator constraints. And auxiliary systems are introduced into the integrated guidance and control models to analyze the constraint effect. An adaptive law is adopted to compensate unknown uncertainties in the varying-time system. The proposed control scheme guarantees the desired interception performance and the stability of the missile dynamics. And nonlinear 6-DOF simulations are included to demonstrate the effectiveness of our approach.
