OZONE CONCENTRATION AND ULTRAVIOLET RADIATION INTENSITY CONTROL SYSTEM DESIGN

摘要：

Ozone concentration and ultraviolet radiation intensity as the plants important stress factors are more and more widely applied in the study.But uv light continuously release ozone which can cause ozone concentration variable, this cannot satisfy the requirements of the single factor in some experiments.Therefore, the real-time measurement and control of the two environmental factors are particularly important.This paper designs a system based on μC/OS-II embedded operating system and chooses LPC2478 of ARM7 series as microprocessor.Through the fuzzy adaptive PID algorithm, ozone concentration is realized real-time control.Compared with the traditional PID, the control accuracy is improved.
