Tv-guided Bombs Control System Design

The article aims at studying the control system of TV guidance bomb, and does the work from three aspects.First, the article designs the servo actuator loop. In order to reduce the expend of the development of TV guidance bomb, it refits the servo actuators of some missile for the servo actuators of the pitching loop and the yawing loop, and then, it tests the characteristic of the actuators and makes the actuators satisfy the basic requests; for the tumbling loop, the servo actuator adopts three-position relay control fashion to make the loop be stable by using the relay control circuit, the three-position and five-passage valve and the gas amplification device.Second, the article designs three stable loops by using the MATLAB/Simulink, and does simulation and analysis. For the pitching loop and the yawing loop are completely the same, the article takes the pitching loop for example to do the analysis. Through the selection of the parameters and the design of the emendation modules, it makes the three stable loops satisfy the designed capability index. And then it discusses the factors which affect the mobile peculiarity of the tumbling loop.Third, at the basis of the simulation and the analysis, it does some preparation for the design of the stable loops. It mainly contains the design of relevant circuit. The article makes preparation for the further study.
