Abstract:

Based on the extended state observer (ESO), the control system for the missile longitudinal plane is designed. Firstly, the elasticity of missile body, the uncertainty of model parameters and the dynamics of measurements are treated as the composite disturbance and an extended state of the system. Then the ESO is used to estimate the states of the extended system，which are used for the feedback of a control algorithm and the design of compensate control. Finally, the closedloop stability of the controller algorithm is proved. Simulation results show that the proposed control algorithm has good command tracking properties and strong robustness.
