Abstract : A novel nozzle controller of spraying robot aiming
toward crop-rows based on fuzzy control theory was studied in this paper
to solve the shortcomings of existing nozzle control system, such as the
long regulation time, the higher overshoot and so on. The new fuzzy
controller mainly consists of fuzzification interface, defuzzification
interface, rule-base and inference mechanism. Considering the actual
application, the fuzzy controller was designed as a
2-inputs&1-output closed-loop system. The inputs are the distance
from nozzle to crop row and its change rate, the output is the control
signal to the execution unit. Based on the design project, we selected
the FMC chip NLX230, the EMCU chip AT89S52 and the EEPROM chip AT93C57
to make the fuzzy controller. Experimental results show that the project
is workable and efficient, it can solve the shortcomings of existing
controller perfectly and the control efficiency can be improved
greatly.
