MATLAB simulation for an experimental setup of digital feedback control;

In the aspect of multiple high accuracy A/D converter, a new type twice sampling A/D converter with digital feedback is talent showing its.

This paper describes a circuit for Hall device, which is used in a digital feedback study system for accelerator control.

Application of a feedback algorithm based on ABEL-HDL language to PLD design;

In this paper,the effect of feedforward algorithm,feedback algorithm and hybrid algorithm are com-pared by simulation,and verified on the experiment setting with the loudspeaker and the fan as the noise source.

Among the digital algorithms presently available for on-line monitoring of the dielectric loss factor of power apparatus,most of them must meet strictly the synchronous sampling criterion,simultaneously with a precondition that the power frequency must be invariable in the sampling periods.

Among the digital algorithms presently available for on-line monitoring of the dielectric loss factor of power apparatus,there are unavoidable limitations that most of them must meet strictly the synchronous sampling criterion,simultaneously with a low calculating resolution.

Most present digital algorithms for on-line monitoring of the dielectric loss factor in power equipment are limited by the assumption of the synchronous sampling criterion which reduces the calculational resolution.

A digital feed forward control scheme for the gradient amplifier in magnetic resonance imaging system (MRI) is proposed in this paper to obtain pulse currents for gradient coils with fast ramp speed and low ripple level.

The universal formula optimized with feedback mutation genetic algorithm was used in evaluating some cases and compared with other methods,results showed that the formula which is simple,comparable,universal and practical is free from the restriction in kinds and numbers of pollutants and easy to calculate.
