Development of the Chopped Speed Regulator for Torpedo Prolulsion Motor

介绍了鱼雷推进电机斩波调速装置的设计原理和电路构成,重点分析了主电路功率模块IGBT的并联与驱动,以及缓冲电路和散热装置的设计。给出了DSP编程的主流程和中断服务程序,并且对传统PI调节进行了改进,引入了带积分修正项的PI调节。实验表明,采用该方案,电机损耗和发热减小,噪声降低,系统的低速性能和动态响应性能得到了改善。

The design principle and schematic circuit of the chopped speed regulator for torpedo DC motor is introduced. The parallel connection and drive of the main circuit power component Insulated Gate Bipolar Transistor （IGBT） are analysed, and buffer circuit and radiator are designed. The main flow chart and interrupt service for the Digita Signal Processor （DSP） prograrnming are given. Traditional Proportional-Integral （PI） regulation is improved by introducing integral correction part. The experimental results of this device show that the motor＇s losses and radiation are decreased, and the system noise is lowered. This control scheme has better dynamic and static performance.
