| Based on the requirement of a practical project, a control system of the terminal guided projectile has analyzed and designed. The principle of the control system is detailed expatiated, and also some relative key technology.The following is the main content of the paper: The pneumatic distribution of the system is analyzed. It is established a pill space motion model of six-degree of freedom and with the theory explanation of all automatic control system. A software which is on the ballistic trajectory without control for the pill in portrait plane is developed. In order to studying the dynamic characters of the pill, the vertical and side direction perturbation equmions of the pill are analyzed. Moreover the transfer functions of the pill are identified. By neglecting the coupling influence, the control laws of pitching, yawing and sloping movements are designed separately with frequency domain analysis, and then the parameters of the controller are chosen. The MATLAB software tool is used to design and simulate the model. Those simulations verify and improve on the control system. At last, the flow chart of control software and hardware designing about the terminal guided projectiled is studied. |
