This paper studies an enhanced adaptive observer to estimates speed and position of the rotor to satisfy the needs of full-speed implement for SPMSM drives.

This algorithm introduces an adaptive observation model under the particle filtering framework,and adaptively chooses the noise variance and the particle quantity according to the errors of tracking and the athletes\' act change margin.

Actuator fault accommodation based on adaptive observer for MIMO system;

Nonlinear adaptive observer design without a priori knowledge on the unknown parameters;

Modified nonlinear adaptive observer based on strong tracking filter;

A method of implementing adaptive enhancement of variance on an image by a recursive low-pass filter is introduced mainly in this paper.

Considering the characteristics of the inconspicuous difference between targets and backgrounds and the low contrast in infrared images,an adaptive enhancement algorithm based on fuzzy particle swarm optimization is used in the infrared image processing.

An edge detection algorithm based on adaptive enhancement is presented in this paper on the basis of the analysis of traditional edge detection algorithm.
