This paper discusses the traditional analog integrator,and introduces a new integrator based on real-time drift compensation schemes.

Method of watermarking based on drift compensation;

Research on the algorithm of drift compensation based on gyroscope with six accelerometers

It is constructed on the basis of a single laser beam and the combined application of technologies of laser holography,laser alignment,laser drift compensation and magneto optic modulation.

Real-time Compensation to Nonuniformity of Image Sensor;

Different compensation algorithms are founded according to the specific parameters of measuring equipments,a real-time compensation program is carried out when the inclining angle is in a certain range,and it was verified by experiments.

Based on the study of the system model in different flight conditions, and by use of real-time compensation in inertial guidance, a method is put forward for selecting the error compensation model and the model of compensation evaluation based on the engineering background.

New Methods of Thermal Error Robust Modeling and Real Time Compensation System for NC machine Tools;

The technology of on-line monitoring and real time compensation of wear is one of the most key technology in modern manufacturing system.

In practical applications, active power filters are difficult to be implemented with real time compensation, because of the time delay of currents detection, power converter circuits and so on.

The simulation results show that the new algorithm can effectively eliminate the integrator drift with higher precision of flux estimation under permanent magnet synchronous motor wave input of EMF.
