The measurement precision and speed have a improvement by combining with single-microcomputer frequency comparison sample technology and sample cycle self-adjustment.

At the same time,the Capture function of AVR is used to do adaptive integral period sampling and adapt the sampling period.

A novel adaptive sampling period algorithm is presented, and the simulation results show its advantage.

Several adaptive sampling period algorithms are studied deeply and some improvements are made.

An adaptive sampling period algorithm based on adaptive grid IMM is proposed.

In view of the character of shearers drum lifting by memory program controlling,this paper analyzes various factors influencing sample period.

The relation of the control error, induced with the sample measurment, to the sample period has been analyzed and the choice of the sample period is also given.

Because there is pure delay time τ in the object , so it is taken to be better choice that the sample period T is equal to pure delay time τ , and some literature persists in this opinion also .

Optimal sampling period selection methed for network control system;

The effect of sampling periods disturbance on discrete linear system;

Maneuvering target model based on small sampling period;

This paper has described the composing of floating-car system,presented a theoretical method for floating-car sampling cycle optimization: regarding speed as a stochastic signal,analyzed its frequency spectrum using fourier transform,and decided the optimal sampling frequency by Shannon sampling theory.

This paper analyzes the causes of error resulted from many ways, such as floating-point arithmetic, temperature, pressure measuring loop, choice of sampling cycle, so that the problems can be noticed.
