This paper will discuss about DC motor speed control based on fuzzy logic control system implemented on
Linux operating system. This fuzzy logic control system can be designed and controlled from remote area i.e.
any personal computer, which use TCP/IP network and http protocol. Range of DC motor speed which is
controlled is 800-2400 RPM. Software is designed by using C language and Perl.
Experiments were done for testing speed of fuzzy logic control process in any server type and condition, and also
the experiments were done for testing the DC motor speed control system in various setting point. The results
show that speeds of fuzzy logic control for AMD K6-2 400 MHz server with 224 MB memory and Pentium 120
MHz with 32 MB memory are 5.8 ms and 16.8 ms respectively. This system had been tested from local
computer and remote computer at setting point 800 RPM, 1600 RPM and 2400 RPM for 90 seconds and system
can control speed of DC motor well. The server computer which has light processes, takes 0.8929 second
sampling time and server computer which has heavy processes takes 0.9646 second sampling time.
