When the missile rotates, there is a coupling problem caused by aerodynamic, inertial, and control cross-coupling in the pitch and yaw channels. This paper presents a dynamic precompensation diagonal dominance decoupling method for control coupling caused by the actuator dynamics. Firstly, the equivalent transfer function matrix of the actuator is obtained, and the influence of the spin rate on the control coupling is analyzed. Secondly, the improved dynamic diagonal dominance decoupling method is obtained based on the diagonal dominance theory and the pseudodiagonalization method. Finally, the actuator function in the quasi–body coordinate system is decoupled by the dynamic compensation matrix solved by the improved method. The simulation and comparison results show that this method has a good decoupling effect. On this basis, the approximate decoupling of the broadband actuator system is achieved by the compensation parameters at different spin rates.
