介绍了宝钢研制的连铸机用矢量控制交流调速装置：采用带补偿的磁通闭环的转差频率法矢量控制，其中磁通、转矩观测模型较多地依赖于定子参数，避开了一阶惯性环节，易于实时计算，受电机参数的影响较小；利用新型马达控制专用微处理器８ＸＣ１９６ＭＣ，采用直接正弦脉冲宽度调制（ＤＳＰＷＭ），简化ＳＰＷＭ设计，快捷地实现电流的实时控制，使电流调节器具有良好的跟踪性能；同时，通过软硬件结合，监视各故障信号，及时进行相应处理，采取有效措施保护器件和装置免遭损坏。
The vector control AC speed regulation device for continuous casting machine developed by Baosteel is introduced. The slip frequency method vector control with flux closed loop with compensation is adopted, in which the flux and torque observation models are more dependent on the stator parameters and avoid First-order inertia, easy to real-time calculation, less affected by the motor parameters; the use of a new motor control microprocessor 8XC196MC, the use of direct sinusoidal pulse width modulation (DSPWM), Simplify the SPWM design, real-time control of the current quickly Current regulator with good tracking performance; the same time, through the combination of hardware and software, monitoring the fault signal, timely and appropriate treatment, take effective measures to protect devices and devices from damage.
