Accurate detection of orbital angular momentum (OAM) is one of the critical techniques for OAM‐related communications. However, conventional OAM identification approaches are often complicated and costly. In this letter, a convenient method based on diffraction neural network (DNN) is presented for OAM states detection in the sub‐terahertz (sub‐THz) regime. The optimal phase distribution of the lens...
This article mainly studies the automotive collision avoidance system based on fuzzy control. This system selects and uses millimeter-wave radar to measure the distance between two cars and the speed of a motor vehicle. First of all, create the safety distance model of the motor vehicle brake. Secondly, design the fuzzy controller for early warning. Lastly, according to the national highway safety...
The optimized theory is used in the electronic control of the power train in order to improve the performance of the car. Except that, the author explains the optimized theory and the method of using it in writing the computer program. And moreover, the author discusses the problems occurring in the object and gives the methods to solve them. The result of the object is expressed by figures and gives...
Basing on input-output linearization strategy, a model of the flexible manipulator can be decomposed into an input-output subsystem and a zero-dynamics subsystem. A fuzzy control is used to input-output subsystem. By analyzing the relationship between the eigenvalues of the zero-dynamics subsystem and the designed parameters in the output of the redefined system, the designed parameters are determined,...
