Intelligent Control for the Variable-Speed Variable-Pitch Wind Energy System
In this paper, a new type of multi-variable compensation control method for the wind energy conversion systems (WECS) is presented. Based on wind energy conversion systems, combining artificial neural network (ANN) control and PID, a new type of PID NN intelligent controller for steady state torque of the wind generator is designed, by which the steady state torque output is regulated to track ...
متن کاملAluminum Ion Implantation Using a Variable Energy RFQ Implanter
High energy aluminum ion implantation has been studied for power semiconductor device fabrications. A new MeV ion implanter system using a variable energy RFQ linac is developed and tested for pulse mode operation. The RFQ linac is driven by an r.f. resonance circuit having an external variable inductance coil and it is tuned so that the acceleration energy of aluminum ions is 0.9 MeV. The ions...
متن کاملVariable photon energy photoelectron spectroscopy of tris-cyclopentadienyl lanthanides.
The gas phase photoelectron (PE) spectra of LnCp3 (Cp = η-C5H5; Ln = Pr, Nd, Sm), measured with a wide range of photon energy, are reported. Resonances observed in the photon energy regions of 4d to 4f excitation enable identification of ion states resulting from 4f ionization. For all three compounds molecular ion states characteristic of both 4f(n) and 4f(n-1) configurations are observed (Pr,...

متن کاملIsomer-resolved ion spectroscopy.
We demonstrate the isomer-resolved spectroscopy of gas-phase ions, with different geometries separated prior to spectroscopic probe using ion mobility techniques. Specifically, ring and chain isomers of carbon cluster anions with 10;-12 atoms have been separated by ion mobility/mass spectrometry and examined by photoelectron spectroscopy. This methodology should also apply to other ion spectros...
