 Considering the weak robustness of dynamic inversion control, an incremental dynamic inversion control law for missiles with tracking differentiator is designed. Firstly, the overload control model of the missile is established, which can be divided into the fast loop and the slow loop. Then through the feedback of state rate, the incremental dynamic inversion control law is proposed for each loop, and its robustness is analyzed. During the design process, the fast tracking differentiator is introduced to solve the immeasurability problem of state rate. Simulation result shows that the proposed control law has excellent robustness.
