Along with the increasing common concerns on global warming and exhaustion of fossil fuels, renewable and environmental friendly energy sources are being considered to be viable for alternative energy. Among them, hydraulic power generation is high-energy density and hence even small-scale generating plants can provide considerable power and can operate with relatively stable condition compared with...
A general recurrent neural network (RNN) with implicit dynamics has been proposed by Zhang et al for online time-varying algebraic equations solving; namely Zhang neural network (ZNN). In this type of network systems, neural dynamics are elegantly introduced by defining a matrix-valued error-monitoring function rather than the usual norm-based scalar-valued error funtion. This makes the computational...
Switched reluctance motors (SR motors) have several desirable features, including simple construction, high reliability and low cost. But large torque ripple and expensive position sensors used in SR motor drive systems are considered as drawbacks for wide application. Several studies have succeeded in torque ripple reduction for SR motors using direct torque control (DTC) technique. In this paper,...
