Abstract :
As for the strong coupling, time-varying and nonlinear characteristics of Bank-to-turn missile system, a control which involves dynamic inversion algorithm, linear quadratic regulator (LQR) and H∞/mixed sensitivity algorithm was proposed. The dynamic inversion algorithm was applied to translate the nonlinear mathematical model of missile system into a pseudo-linear one. Linear quadratic regulator (LQR) realized optimal control through state feedback. H∞/ mixed sensitivity algorithm tackled the possible uncertainty in the mathematical model. Simulation of the closed loop control system was implemented via Matlab / Simulink software, from which the results showed that this control strategy could obtain desirable performance.
