As the world shifts to using renewable sources of energy, wind energy has been established as one of the leading forms of renewable energy. As the requirement for wind energy increases, so too does the size of the turbines themselves, where the latest turbines are 10 MW with a turbine diameter in excess of 190 m. The design and manufacture of the blades for these turbines will be critical if ...
2016-4-1 · The upper limit ensures the continuous conduction mode while the lower limit keeps the zero in LHP. Unlike the IAC model, the state-space averaged model does not include a T s term, and therefore does not predict this regime of stable operation. As the frequency approaches infinity or T s approaches zero, the state-space averaging model and the IAC models converge to the same model [].

2018-8-1 · Abstract. Particle swarm optimization (PSO) is a population based meta-heuristic search algorithm that has been widely applied to a variety of problems since its advent. In PSO, the inertial weight not only has a crucial effect on its convergence, but also plays an important role in balancing exploration and exploitation during the evolution.
Gravitational Search Algorithm (GSA) is a widely used metaheuristic algorithm. Although fewer parameters in GSA were adjusted, GSA has a slow convergence rate. In this paper, we change the constant acceleration coefficients to be the exponential function on the basis of combination of GSA and PSO (PSO-GSA) and propose an improved PSO-GSA algorithm (written as I-PSO-GSA) for solving …
2021-6-22 · Kinks refer to non-differentiable parts of an objective function, introduced by functions such as ReLU ( max(0, x) ), or the SVM loss, Maxout neurons, etc. Consider gradient checking the ReLU function at x = − 1e6. Since x < 0, the analytic gradient at this point is exactly zero.
