摘　　要：针对连铸拉矫机电机负荷分配不均的实际问题,基于异步电机矢量控制技术,对负荷分配的机理进行研究,建立连铸机动态等负荷分配控制系统模型,并将该模型应用于生产实际。结果表明:该控制模型实现了拉矫机各电机负荷的动态均匀分布,稳态误差小于5%,最大调节时间为4.8 s,整个响应过程无大超调现象。Since there is unequal load sharing problem in withdrawal straightener motors of continuous caster, mechanism of load sharing was studied based on asynchronous motor vector control technique. Dynamic and equal load sharing control system model for continuous casting machine was established, and applied to production practice. Local experiments show that dynamic and equal load sharing of each motor was achieved by this system, stable error was less than 5%, maxinum regulation time was 4.8 s, and there was not serious overshoot in full respond process.
