ABSTRACT: The application of BLDC
motor drives in industries is becoming more popular nowadays. An error will
occur in the drive that is originated by some disturbances which are the major
problems to reduce the stability of the system. To obtain the minimum
performance index, the optimal control signal is formulated, which is the main
objective of this paper. Based on quadratic performance index, the optimal
control system of BLDC motor drive is a design which spotlights in this paper.
The complexity of the mathematical expressions has been reduced by using state
space approach to the BLDC system. The burden to the control engineers has
reduced based on tedious computation by using thus optimal design. To provide
the desired operating performance, this optimal design helps to realize the
BLDC system with practical components.
