To reduce the torque noises of brushless dc motor, a new hybrid vector control strategy has been proposed based on hall signals. Experimental results verify that this method implemented in micro electric vehicle not only reduces the torque ripple but also run at high-performance vector control. It works reliably in complex working conditions with excellent low speed start-up performance as well.
Wireless mesh networks (WMNs) consist of mesh routers and mesh clients, where mesh routers have minimal mobility and form the backbone of WMNs. They provide network access for both mesh and conventional clients. Wireless mesh networks is put forward as one important technology of the access of various broadband. The integration of WMNs with other networks such as the Internet, cellular, IEEE 802.11,...
