Helicopter Control Energy Reduction Using Moving Horizontal Tail

The Scientific World Journal, 2015
Helicopter moving horizontal tail (i.e., MHT) strategy is applied in order to save helicopter flight control system (i.e., FCS) energy. For this intention complex, physics-based, control-oriented nonlinear helicopter models are used. Equations of MHT are

Simultaneous exact controllability for Maxwell equations and for a second-order hyperbolic system

Electronic Journal of Differential Equations, 2010
We present a result on "simultaneous" exact controllability for two models that describe two hyperbolic dynamics. One is the system of Maxwell equations and the other a vector-wave equation with a pressure term.
