This work is aimed at optimizing the wind turbine rotor speed setpoint algorithm. Several intelligent adjustment strategies have been investigated in order to improve a reward function that takes into account the power captured from the wind and the turbine speed error. After different approaches including Reinforcement Learning, the best results were obtained using a Particle Swarm Optimizatio...

in this paper the speed gradient method is applied to design an adjustment algorithm for parameters of neural network controller. Local quadratic criterion expresses generalized error of desired trajectory tracking. Continuous adjustment laws for neural network parameters and their discrete analogies are derived on base of speed gradient method. To illustrate an approach, the mathematical model...

The rapid increase in Internet communications’ products such as high-speed switches, SerDes (serial-deserializer) elements and XAUI (X=10G, attachment unit interface) ports has energized the need for process technologies that support both digital and analog (mixed-signal) elements at radio frequencies (RF). In order for these products to be competitive, process technologies that support analog/...

On the basis of the ideas of Goldman and Beja(1980) and Chiarella(1992), we construct a stochastic model of speculative dynamics that has a stochastic equilibrium. In this model, different expectations for the price of fundamentalists and chartists are introduced into the model. The system is analyzed using concepts and techniques from the theory of Random dynamical systems. The model exhibits ...

This study investigates the effect of intra-organizational and macroeconomic factors on banking leverage in selected Iranian banks. For this purpose, after calculation of the Banking Leverage for each bank, by using Random-Coefficients Approach (Swamy model), the impact of explanatory variables during the period of 1999-2016 was examined separately by 10 selected Iranian public and private bank...

Firms adjust their capital structures to avoid financial distress and bankruptcy sustain in the market. Asian firms have significantly different patterns than USA European counterparts. The moderation model gains a better understanding of relationship between variables. We tested moderating roles life cycle stages macro-economic factor gross national income per capita find impacts on speed adju...
