The Inversion Method In The Design Of The Small Smart Bombs Btt Controller Applied Research

Based on the Small Smart Bomb (SSB) and the view of practical engineering, this thesis investigates the backstepping design method of the nonlinear control and explores some related issues on the design of bank-to-turn controller for SSB. Major research work of this paper includes the following aspects:Firstly, according to the actual object, this thesis establishes comparatively accurate mathematical model of small smart bomb and applies the backstepping design method to the BTT controller designing of Small Smart Bomb. Contraposing the nonlmearity, coupling and uncertainly of system, we have completed detailed simulation experiments to verify the performance of backstepping-controller. The simulation results indicate that the backstepping controller we designed has excellent tracking, decoupling and robust performance.Secondly, in order to promote the further practical application of engineering, this thesis adopts the CDT design method to complete the designing of the discrete BTT controller. Meanwhile, the big long step simulation of the closed loop sampling control system verifies the control performance of the discrete controller.The simulation results indicate that the discrete controller we designed acts effectively on the SSB control.Finally, the hardware and software design of the BTT control system has been discussed preliminarily. The algorithm of backstepping control has been focused on and the program with C language is completed.The research results of this thesis provide an effective method for designing BTT controller of SSB, which are of great value in theory and application.
