The Fuzzy Control Policy Implementation of Software and Hardware Adopted in Automatically Changing Receiver System of 25m Radio Telescope

It is difficult to control a system based only on its precise mathmatic model by classical control policy in the condition that their precise mathmatic models can not be found and their parameters are variable in outer environment. With the rapid development in software and hardware, a system using the fuzzy control policy can get very good effects in some conditions. According to the system environment, fuzzy control policy is selected to implement automatically changing recievers in the base of PC hardwares and Windows2000/XP operation system.
