| Summary: | Wheel Drive Electronics is a Brushless Direct Current motor control module
attached to a reaction wheel. Reaction Wheel is commonly used by spacecraft for
three-axis attitude control. The model of Wheel Drive Electronics is made for
automatic measuring instrument test materials. The Wheel Drive Electronics model
is implemented using a 3 phase half-bridge Integrated Circuits and Arduino
microcontroller, with the commutation method used is six-step commutation. The
Wheel Drive Electronics test model that is made has some of the basic features of a
WDE such as speed control, current control, internal measurement, and
communication functions with a Personal Computer. The Wheel Drive Electronics
model is tested by giving commands via a Personal Computer and comparing the
results of its internal measurements with a measuring instrument. The data
compared are in the form of measurement results for velocity, current and
temperature. From the result, temperature sensor has resolution of 0,001°C +/-
0,209; current sensor has resolution of 0,01 mA +/- 87,66; speed sensor with
average different value of 12 RPM +/- 67; speed control performance withaverage
steady state error of 172 RPM +/- 81 and -24 RPM steady state error; 3,544 %OS;
and 60 ms settling time on set point of 4000 RPM.
