Measurement and analysis of the pulsed magnetic field phase lag in the ceramic case;

But the phase lag based hysteresis model is mainly applied in approximation of the main loop.

Three main factors,which influence the phase property of piezoelectric micro actuators and their corresponding phase lag,are analyzed.

Study of phase-lag algorithm for unsteady flow of compressor;

The fact is that the AQM controllers possessing the phase-lag property can eliminate the bias against bursty flows.

Aiming at the phase delay phenomenon occurs in electro-hydraulic servo system corresponding to a sinusoidal input,based on Adaline neural network,adaptive phase corrector was designed for eliminating phase delay using LMS adaptive filtering algorithm.

The phase delay of the Reynolds stress and the wall pressure fluctuations at the scales of coherent structures corresponding to the strain rate of the large scale structures in turbulent boundary layers have been studied.

Because of the uncertainty of reference variety,single prediction algorithm may cause big current overshoot or phase delay in different reference variety conditions.
