Design Of Precise Airborne System Based On Fuzzy Control

Accurate airborne is to ensure that,the airborne objects fall as far as possible within the target area.the target area is a circular range,whose center is the target point,and radius is the established drop accuracy.The weather and ground conditions in airborne have a very high demand.The wind speed and visibility will have a great impact too.Under normal circumstances,the airborne in the short airborne time basically rely on their own to determine the height of the data.However,in low visibility or nighttime environment,airborne judgments on these important data will become very difficult,which will also affect the safety of airborne personnel and the accuracy of landing points,which will lead to effective combat can not quickly build up.In this paper,I study the descent process of the airborne unit,and find that the process has many uncertainties,which are influenced and disturbed by many factors such as wind speed.Fuzzy control can achieve effective control of complex objects,which is difficult to establish by precise model.It is not sensitive to the change of parameters,and has strong robustness,which is suitable for solving complex control problems,which are difficult to solve effectively by traditional methods,such as time-varying and nonlinear.Therefore,based on the fuzzy control strategy of the framework,the airborne unit is controlled.In this paper,the Simulink model in motion process of the airborne unit is established,the control object is fuzzified,and the membership function and the fuzzy rule of the fuzzy controller are designed.Writing the C language file is to verify good control effect of the controller.Based on the fuzzy controller strategy,analyze the movement of the airborne unit,and compare the landing accuracy with controller or no controller.The boundary conditions under the action of the controller are deduced.The results show that under the action of fuzzy controller,the control object which is difficult to establish a precise model,can have a good anti-jamming capability.so that the airborne unit can operate in low visibility or night environment,and have a good Landing accuracy.
