N2 - For a reentry warhead with single moving mass, the goal of control in this paper is tracking and stabilization in roll and yaw channel, respectively. Firstly, a detailed model of warhead is established using Kane method, and the affine nonlinear form for the control design is derived. Then PID is combined with the nonlinear dynamic inverse to form the attitude controller of the warhead. And the disturbance observer based on extended state observer (ESO) is designed, which is used to observe and compensate for the inaccuracy of the under-actuated controller. The Moving Mass Nonlinear Controller (MMNC) is composed of the controller and the disturbance observer. At last, simulation and comparison are carried out, the results show that the MMNC has better system response, better adaptability and stronger robustness than the traditional PID controller.
