ABSTRACT:
The design of a wireless water level
control system is introduced and discussed in detail. In this system, the
wireless Proportional Integral (PI) controller is developed using the LabVIEW
graphical user programming language. Zigbee wireless technology is chosen for
the wireless data transfer system. The experimental testbed was built and the
system software and hardware were implemented. In order to compare the
performance of the wired and wireless system, a corresponding wired water level
control system was built. Experimental results show that under the same PI
parameters, the settling time of the wired system is 3.3 times faster than the
wireless system. However, the percent overshoot using the wireless controller
is 4% smaller.
