Design of Decoupling Control System for Glide Extended Range Guided Munition Based on PID Neural Network

For the existing control coupling between pitch and yaw channels in low-speed rotation of the glide extended range guided munition, this paper describes the dual-channel decoupling control design using PID neural network. To this end, the paper first describes the dynamic model of glide extended range guided munition, based on the analysis of the model a structure and calculation method of PID neural network,is proposed , and it is improved by modified weight which uses in- creasing momentum term and adaptive variable learning rate. On this basis, through particle swarm optimization algorithm the initial weights of the network is optimized. By simulation through Matlah and analysis of the results ,it can be obtained that the method designed satisfies the requirements of decoupling control system, and can rapidly approaching the control target, at the same time it can well overcome the impact of the control system caused by the changes of missile aerodynamic parameters in different Maehes,so a better control results can be achieved through this design.
