Hybrid electric vehicles (HEV) enable higher fuel-efficiency compared to conventional vehicles. The main potential for fuel efficiency lies in the choice of torque split between the internal combustion engine and the electric motor and the gear shifting strategy. In the framework of a predictive control strategy, the vehicle velocity can be considered as another degree of freedom. To achieve mi...

This paper investigates optimal power management of a fuel cell hybrid small unmanned aerial vehicle (sUAV) from the perspective endurance (time flight) maximization in stochastic environment. Stochastic drift counteraction control is exploited to obtain an policy for that coordinates operation and battery maximize expected flight time while accounting limits on rate change output orientation d...

background and aims: the world is threatened by disease outbreak that reaches a public health emergency of international concern, studies to inform public and agencies for effective containment strategy are necessary. several studies provided vital information of the dynamics and control of ebola epidemic outbreak in west africa. methodologies and techniques in those researches have to be revie...

‎in this paper we introduce a numerical approach that solves optimal control problems (ocps)‎‎using collocation methods‎. ‎this approach is based upon b-spline functions‎.‎the derivative matrices between any two families of b-spline functions are utilized to‎‎reduce the solution of ocps to the solution of nonlinear optimization problems‎.‎numerical experiments confirm our theoretical findings‎.

in this article, vehicle cornering stability and brake stabilization via bifurcation analysis has been investigated. in order to extract the governing equations of motion, a nonlinear four-wheeled vehicle model with two degrees of freedom has been developed. using the continuation software package matcont a stability analysis based on phase plane analysis and bifurcation of equilibrium is perfo...
