The scheme proposed by Ortega et al was shown to perform adequate for the torque control problem but when applied to the speed tracking problem, it requires the very rigid assumption that the load torque is a known smooth and bounded function with known bounded first derivative [4].
PBC can be applied to systems described by Euler-Lagrange(EL) equations, so consider the DFIG model(1) and (2) described by the EL equations of motion (3) where ,,, ,, , ,, , ,,.
In the DFIG model EL equations(3), the first term in the left side is the control force, the third term in the right side is the dissipative force, and the second term in the right side is the configurable ‘workless forces’, in which is skew-symmetric and satisfied
It can be concluded that the workless forces , which appear in the EL equations of the DFIG, have no effect on the energy balance function.
Conclusion Based on the analysis of EL system model of the DFIG in wind power systems, a PBC method for solving the output feedback global tracking problem is developed.

Recent work of El Mrabet et al. classified tribological behavior of the magnetron sputtered W-C coatings co-doped with carbon into three regions: adhesive wear region when COF >0.8 and C content is low, intermediate behavior characterized by an abrasive wear (COF = 0.3-0.6) and self/lubricated wear for COF< 0.2 and excess of free carbon [9].
Thus, no obvious correlation was observed among COF, nanohardness and wear behavior despite direct correlation is assumed from the analysis of El Mrabet [9].

The mechanical properties of the PFRP material were provided by Boonsuan et al. [4].
Five tensile coupons cut from the test specimens were tested in accordance with ASTM D3039, in order to determine EL.
From the coupon test, it was found that the average values of EL and GLT were 35.20 GPa and 2.18 GPa, respectively.
Since the PFRP material is usually considered as orthotropic and homogeneous material, characterized by two independent elastic constants: the longitudinal tensile modulus of elasticity (EL) and in-plane shear modulus (GLT).
Also, the orthotropic effect of the material with EL/GLT ratio of 16.1 does not play an important role on the critical buckling moment of the beam.

By using the homotopy analysis method, Babolian et al. [3] studied the numerical solutions of BE.
Pettersson et al. [4] used a polynomial chaos expansion approach to give a numerical analysis of BE in the presence of uncertainty.
El-Hawary et al. [5] used a mixed spectral spline approach to solve the generalized Burger’s equation (GBE).
Based on a spectral domain decomposition approach, Golbabai et al. [6] solved the numerical solutions of GBE.

El-Sawy et al. [1] was the first to investigate the transition from elastic buckling FE to plastic collapse Ffail.
Shanmugam et al. [2] investigated the ultimate load (Ffail) for several boundary conditions for square plates containing a single central hole.
The influence of the yield stress is investigated by El-Sawy et al. [1] and Maiorana et al. [5].
Recently, Scheperboer et al. [8] investigated the ultimate resistance of aluminium plates containing one central hole and a perforation pattern of several holes equally distributed over the plate.
