Brushless DC motors have the features of nonlinearity, multiple variables and strong coupling. The control algorithms of conventional control systems have limitations and can seldom achieve expected control effect. According to the operation requirements of some special underwater vehicles, a brushless DC motor control system is designed in this study. Based on the digital signal processor (DSP), the complex programmable logic device (CPLD) and the intelligent power module (IPM), an advance commutation control algorithm is used to meet the ever increasing computation speed requirement as well as the real-time logic processing requirement, so that the logic processing process is simplified and the high efficiency operation of the brushless DC motor is achieved. Experiments show that the motor system efficiency reaches as high as 92%, with good stability and flexibility. This system can be used as the brushless DC motor control device for special underwater vehicles.
