Wireless sensor networks(WSNs) have been increasingly available for large-scale applications in which energy efficiency is an important performance measure. These applications include environmental monitoring and structure monitoring which demand multifarious data. Driven by the energy limitation nature of WSNs lots of research works have been done(More)
The aim of this paper is to design an attitude controller of an unmanned helicopter using h-infinity and loop-shaping methods. A pre-compensator and a post-compensator are selected to modify the singular values of the normal system to get a desired loop shape. The h-infinity feedback controller is synthesized and the stability margin is calculated. The(More)
