| In the paper, in view of the characteristic of shell/missile's control and guide, mainly research the control system for a given shell. Firstly, the principle of the control system of mortar is detailedly expatiated. Including the design of aerodynamic force layout, the selection of control electromotor and the decelerate setup. Then confirm the controlling way, using DSP to design the circuit diagram for electromotor controlling. In order to studying the dynamic characters of the pill, the vertical and side direction perturbation of the pill are analyzed. Moreover the transfer functions of the pill are identified. A software which is on the ballistic trajectory without control for the pill in portrait plane is developed. The emphases is building the model of the control system, the MATLAB software tool is used to design and to simulate the model, and it proves that the model is fit for the request and performance. At last, design software and hardware of the control system in the mass. |
