摘要
新技术的发展给电机控制行业带来新的发展机遇。从电机控制器、无速度传感器技术方面,介绍了国内外无速度传感器感应电机控制系统中这两个领域内的研究现状及发展趋势。回顾了DSP处理器的发展历程,介绍了DSP的发展现状,从设计和应用角度分析了DSP的特点,介绍了DSP的发展前景;分析了无速度传感器技术的研究现状,指出电机低速下速度估计性能差及低频范围稳定运行问题是目前无速度传感器技术的研究热点,并提出了相应的解决方法。
The development of new technology brings new chance of motor control industry. This paper discusses the actuality and development trend in the motor controller and speed sensorless techonology of motor control system. It introduces the past and the present of DSP processor,the characteristics of DSP are investigated from the viewpoint of design and appllcation,it predicts the future development of DSP architecture. The paper analyzes the present of speed matlon performance and the low - frequency instability are the current introduced. sensorless techonology,indicates that the bad low speed estiresearch focus, the methods to solve the two problems are
