摘　　要：针对飞剪机在剪切区域内剪刃的水平速度要严格保持与带材速度同步问题,提出速度前馈补偿与滑模变结构相结合的复合控制方式,设计了抖振小、响应快的鲁棒速度控制器。结果表明,控制器能明显削弱抖振,提高稳态精度,并对突加负载和系统参数的变化有较强的鲁棒性。In view of the question that the horizontal speed of shear blade demanded strictly maintain synchronous speed with plank in shear zone, a feedforward compensation controller including sliding mode controller is proposed as the velocity controller to improve the system performance, which has the merit of the small chattering and good robustness. The simulation shows that this method improve dynamics and robustness of system effectively despite of load abrupt change and system parameter change.
