Bifurcations are performed for a power system model consisting of two generators feeding load, which is represented by an induction motor in parallel with capacitor and combination constant impedance PQ load. The reactive the coefficient load used as control parameters. response undergoes saddle-node, subcritical supercritical Hopf, cyclic-fold, period-doubling bifurcations. latter culminate chaos. chaotic solutions undergo boundary crises. basin boundaries may consist stable manifold saddle...

Photovoltaic based reverse osmosis desalination systems (PV/RO) present an effective method of water especially in remote areas. The increase the feed temperature leads to amelioration plant performances. Thermal Collector (PV/T) represents ideal power source as it provides both electric and thermal energies for process. Nevertheless, PV/T RO plants should be controlled order solve operation problems related electrical efficiency, membrane, produced rejected salts. This paper suggests a...

In this paper, a nonlinear backstepping controller has been designed to control bifurcation as well incipient chaos that experienced in the RCLSJ (shunted resistive-capacitive-inductance) Josephson-Junction. The results show system, without controller, dangerous Hopf point lead chaotic behavior. For certain values of external direct current (I <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">0</sub> ), system becomes chaotic. On other hand,...
