ABSTRACT

In this project the development of an automatic fuzzy logic controlled motor
of vacuum cleaner is presented. The vacuum cleaner controller has one input and one
output system. The input is a distance which is two set of infrared sensors are used to
detect the range of the dust, and the output is the speed of the motor to suck the dust.
For the embedded fuzzy logic controller, the behavior must be approximately
encoded for the target processor, and then downloaded to the chip for execution. The
target system is a small vacuum cleaner with an embedded microcontroller based on
a Microchip PIC 16F877A microcontroller. The vacuum cleaner is driven by a de
brush motor. Two sets of infrared sensor are used for the vacuum cleaner - one set is
used to detect far distance and the other for detect near distance. The vacuum cleaner
has five circuits to control its operation such as transmitter circuit, relay circuit,
controller circuit and two power supply circuits. Since ali the control circuitry .and
computation are embedded in the vacuum cleaner, it is self contained and start sucks
the operation. The detection of a dust by the sensors activates the controller which
simply attempts to start the operation. Once start the operation, the vacuum cleaner
will start to suck dust and attempts to adjust the speed by comparing the distance.

The fuzzy logic algorithm and PIC controller are use to control the operation of the
vacuum cleaner.
