On the Analysis and Optimal Control Design of BLDC Drives

Now a day’s Brushless DC motor drives are becoming more popular in industrial applications. The major problem in BLDC drive system is that some disturbances are originated in the drive which will results in errors and reduces the stability of the system. The state variables and control variables of the BLDC drive system are synthesized in this paper. The main objective of this paper is to formulate the optimal control signal which results in minimum performance index. This paper spotlights the design of optimal control systems for BLDC motor drive system based on quadratic performance indexes. This state-space approach to BLDC system analysis reduces the complexity of the mathematical expressions. This optimal design will reduce the burden of tedious computations in control engineers. This optimal design helps to realize the BLDC system with practical components which will provide the desired operating performance.
