Compared with position tracking method, circular orbit tracking method is not influenced by the unevenness of apparent motion and has highly tracking precision.

Backstepping position tracking control for permanent magnetic synchronous motor servo system;

Neuron adaptive PID control for position tracking control of automatic clutch;

This paper provides a position tracking system with distributed computers for dynamic target real-time monitoring of personnel and mobile equipment in coalmines underground.

The gestures of real palm that obtained by position tracker are mapped to the gestures of virtual palm in the virtual reality environment by data mapping and transfer matrixes.

Aiming at the problem of "collapse" of the insulating materials(such as plastic film,paper,etc)when slit into the strips,a position tracking mechanism of arranging and rewinding slit strips basing on servo control technology is developed.

The position tracking controller with good performance is the guarantee of high precision brushless DC motor ser-vo system.

In order to eliminate the measurements of rotor flux and rotor velocity, a scheme of position tracking control of induction motor based on flux observer and rotor velocity observer is presented in this paper.

According to the characteristic of the position tracking system, this paper describes an adaptive controller based on a single neuron, which can be used to a position tracking control in CNC systems.
