ACKNOWLEDGEMENTS
My sincere gratitude goes first to my Creator. Though it has been such a journey
academically, He has been my Sufficiency and my Help in times of need. “He
knows me well”
Mr and Mrs Oguntoyinbo, myparents, deserve all the credit for their support both
in kind and in cash; they have been there all through my life voyage prayerfully
for me. Their patience is greatly appreciated.
To my supervisor, his view that everything is simple still amazes me even when
the “stuffs” are serious nuts to crack. I am grateful for his service.
To my technical friends, Ifeta Adekunle and Frej, your technicalsupports are
worthy of appreciation. You made a part of my story.
To my friends and personal friend, you are worthy of my kudos.
Thank you!

This report presents a PID model of a brushless dc (BLDC) motor and a robot
trajectory planning and simulation. A short description of the brushless dc motor
is given. For this work, mathematical models were developed and subsequentlyused in getting the simulation parameters. The PID model is accomplished with
the use of MATLAB®/SIMULINK®. The operational parameters of the specific
BLDC motor were modelled using the tuning methods which are used to develop
subsequent simulations. The best PID parameters were thereafter used for the
robot trajectory and simulation over a football pitch model.
