Introduces the design method of a novel impedance transformer, proved its superiority, then optimized this new design method using optimized means, and designed the new optimized impedance transformer whose size smaller about 20 percent and bandwidth wider than the traditional stepped impedance transformer. Therefore, to simplify the design of ladder-impedance transformer and make its broadband larger and its size smaller is very meaningful for the microwave integrated circuits.
Feedforward - Improve PID algorithm is an effective method of intelligent vehicle control, the algorithm not only enables the intelligent vehicle system with a good dynamic performance and speed of response, but also improves the adaptability and robustness of the system, making the intelligent vehicle able to stably operate on different runways at a faster speed. This method has good application prospect.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
