Abstract  Aiming at the problem of vibration shock caused by clearance to the left and right adjusting mechanism of blade roll mill, a dynamics model of the roll adjusting mechanism was established, and it was decoupled by the differential geometry feedback linearization method. On this basis, a sliding mode controller based on interference observer was designed, and tracking simulation of the sliding mode control process was accomplished by MATLAB/Simulink software. The sliding mode control algorithm was applied to blade rolling site, and the effectiveness of sliding mode control was verified. The results showed that the system trajectory could be tracked with high precision by using the sliding mode control algorithm based on interference observer. The designed sliding mode controller can realize the control of the roll adjusting mechanism well, improve the roll position adjusting precision, and thus improve the machining precision of the blade.

考虑间隙的叶片辊轧机轧辊调整机构滑模控制研究

针对间隙对叶片辊轧机轧辊左右调整机构造成振动冲击的问题，建立了轧辊调整机构的动力学模型，采用微分几何反馈线性化方法对该动力学模型进行线性化解耦处理。在此基础之上，设计了基于干扰观测器的滑模控制器，利用MATLAB/Simulink软件对滑模控制过程进行跟踪仿真，并将滑模控制算法应用于叶片轧制现场，验证了滑模控制的有效性。研究结果表明，采用基于干扰观测器的滑模控制算法可以实现系统轨迹的高精度跟踪。所设计的的滑模控制器可以很好地实现对轧辊调整机构的控制，提高轧辊位置调整精度，从而提高叶片加工精度。
