The L-Band Digital Aeronautical Communication System (LDACS) is a typical pilot-aided orthogonal frequency division multiplexing (OFDM) communication system. With the performance of LDACS in the Unmanned Aerial Vehicle (UAV) over-water channel, the pilot is redesign based on Zadoff-Chu (ZC) sequence. The new periodic ZC-pilot could reduce the effects of noise by correlated calculation. Based on new...
In this paper, the complicated motion equations are established based on the dynamic characteristics of the return flying vehicle. This model is incorporated into an optimal control formulation that includes constraints on both the vehicle and mission parameters, such as the height, velocity, range, heat rate, aerodynamic load and dynamic pressure capability. How these models are appropriately employed...
At present, there is a more popular topic to do research about hard target and underground target. More and more precision weapons equip with penetration warhead. But to show the best penetration performance, there should be a strict terminal angular constraint. Thus, the research about trajectory and terminal guidance law of penetration missile will supply more theoretical basis for the design of...
To achieve intelligent control algorithm in Foundation Field bus process control system, a method which combines Lab VIEW and MATLAB to design a real time intelligent control system is presented in this paper. The single neuron PID control algorithm programmed in MATLAB can be stimulated by Lab VIEW SIT, the communication between Lab VIEW and field bus instruments can be established by OPC Server...
