Taking an air conditioning system with two identical chillers in parallel as an example, analyses the performance of the chillers under part load conditions, and points out that the cooling output of the system shall be only equally shared by the two chillers if the outlet temperature of chilled water is not reset, and that a master-slave control mode can not be adopted.

A master-slave control surgical robot system was developed for minimally invasive laryngeal surgery in this dissertation.

In the viewpoint of remote welding noncontact application, concise and flexible master-slave control strategy was applied.

The master slave controlled inverter parallel system is composed of three inverter modules.

Under the specific condition that the exterior mechanism can not be improved, through analysis, the original master slave control mode is replaced by single-to-single control mode, so that the problem of frequent trip of driving motor is solved successfully, and the machine accidents like gear beating are eliminated, making the equipment operating smoothly.

Configuration and master/slave control principle of ultra precision wafer stage were introduced.

For this,in the paper,for the periodic motion characteristic of the dual linear motor,on the base of considering the tracking performance and the stability,the master/slave control and the repetitive control are adopted to compensate for the periodic error,so that dual linear motor can keep exactly synchronous motion.
