Abstract: In this paper, a technique for the remote control of chopper based DC motor is proposed. The main objective of the remote laboratory is to facilitate the students to avail the laboratory experiments 24x7. This paper explains the remote control operation of chopper based DC motor. Chopper is a power electronic DC-DC converter which converts fixed DC voltage to variable DC voltage. This variable DC voltage output of chopper is fed to DC motor armature terminals. Arduino uno is interfaced with LabVIEW to generate pulse width modulated(PWM) signals. The duty cycle of the PWM signals is controlled to control the output voltage of chopper. Remote control can be achieved either by team viewer or setting up an individual server. The simulation of DC motor control using chopper is carried out in MATLAB / Simulink.
