Design of BTT control technology for cruise missile based on LQR

Based on the LQR optimal control, a method for the BTT control of cruise missile was proposed. The mathematical model of the cruise missile based on the aerodynamic externality and aero characteristic was established. Then choose the appropriate state variable follow the design request of the control. Design the optimal control law based on the integral LQR. The simulation results show that the missile can track the command of the acceleration and roll without error, and also restrain the appearance of the sideslip.
