Now-a-days, 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. 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.
