Fuzzy Control of the Spraying Medicine Control System

The continuous spraying was adopted by most of spraying pesticide systems, which can not accord to the extent and the characteristic change of targets to automatically regulate dose of drugs. This way not only resulted in waste of pesticides, but also caused pollution of environment. The designing studied the variable spraying pesticide system of real-time, which based sensory technology, at the same time, fuzzy control was applied in this system. The paper introduced the composition and control principle of the spraying pesticide system, at the other hand, the linking of Simulink and the fuzzy controller was introduced by this paper. Fuzziness of inputs and the outputs, the determination of subordinate functions, the establishment of fuzzy controlling rules and fuzzy control simulation of the spraying system were designed. Simulating result indicated that transiting time is short and the system is steady.
