摘　　要：双闭环直流调速系统广泛应用于带钢热连轧等复杂工业过程,该文针对轧机传动系统由于咬钢过程导致的调速系统动态性能下降问题,建立主传动系统机电耦合模型,并利用基于残差生成器的容错控制框架,进行主传动系统的动态补偿控制器设计。选取控制器输出和调速系统输出作为目标控制函数的性能指标约束,采用基于梯度下降的数据驱动方法,实现动态补偿控制器参数矩阵的在线迭代优化,提高电机调速系统在负载扰动影响下的鲁棒性能和抗干扰性能。仿真与实验结果均表明:该算法能够减少电机转速下降幅度,改善传动系统调速性能,提高闭环控制系统稳定性,并能有效缩短带钢头部长度。The double loop DC motor speed control system is wildly used in complex industrial process, such as the hot strip rolling process. This paper dealt with the dynamic speed drop problem during the steel biting period of main drive systems in hot tandem rolling mills. The electromechanical coupling model of the main drive system in rolling mills was established, the dynamic compensation control algorithm was proposed based on the data-driven design of the observer-based residual generator control framework, by selecting controller output and system output as performance indices of the cost function. Then, the controller parameters can be online optimized by a gradient-based data-driven method, to improve the performance of system robustness and disturbance rejection. Through the case study, it can be seen that our proposed algorithm can simultaneously reduce the motor speed decline, improve performance of transmission control systems, increase the closed loop system stability, and effectively shorten the length of strip head.
