Abstract
The uses of brushless DC motor in quad copter application gives rise to a new
demand. Quad copter drone usually uses brushless DC motor due to high performance,
high efficiency and small volume. The function of brushless DC motor in quad copter is
for positioning and velocity of the drone itself. Surely brushless DC motor gives more
efficiency and effectiveness compared to brush motor. In order to analyse the responses
of the brushless DC motor and control strategy for quad copter applications, black box
modelling is invent. Black box or known as experimental modelling is a method for the
development of process database of the models. Since physical simulation cost so much
times, black box modelling is a common way to gain the overall behaviour process input
and output. Typically, the built model used for estimation of potential process values or
in application for process management. Important aspects in black box modelling which
is system analysis, data conditioning, key variable analysis, model structure design,
model identification and model evaluation. Software that been used is MATLAB and
Simulink. The MATLAB and Simulink software used to demonstrate and measure the
effective performance of the concept. The software helps in designing and identification
of the system of the quad copter. Usually, the performances of different linearity of the
models give different results of the models. Surely, linear transfer function models gives
the best result for the simulation.
