volume controller
1.It is shown from the experiments that the designed controller has the characteristics of high reliability,good real-time,high EMC,small volume,low cost and simple implementation,whose foreground is wide in application.
2.The RAID50 model of multi-controller stripe and the two-level address mapped mode of the host virtual volume address to high array and low array stripe is designed for enhancing I/O access concurrency.
3.The main research in the dissertation is the design of TT&C communication controller of the lunar rover, which can makes the measure and control, and data traffic among the rover, lander and ground station becomes available, and which can ensure the security in the limited condition of volume and power.
4.The rotation control technology in the laser gyro strapdown inertial navigation system was studied.The method of realizing closed-loop digital control with RLG located in the strapdown inertial navigation system was discussed.The structure of rotation servo system was introduced.The designing method and process of the digital controller were given.The method of implementing digital controllers by means of computer and software flow were demonstrated.The result of simulation and debugging of this system showed that it fullfills the requirment of the strapdown inertial navigation system.It assures the stability of rotation and solves the problem of striking without increasing the volume and cost of the system.
