Multi-frequency sample tracking control system

This paper studies multi-frequency feedback sampling data system. The paper first proposes that a high sampling controller is designed in the low sampling frequency system. The multi-frequency sampling control system cannot be limited by the low sampling frequency, thus the system bandwidth can be extended, the ripple of the system can be reduced and the response speed of the system can be improved. The output fluctuation appeared during the sampling intermittence can be smoothed by the multi-frequency sampling controller. The stable time of the system, stability and instantaneity of the system can be improved by the controller.
