摘　　要：通过对驱动斜轧穿孔机狄塞尔导盘液压系统的分析,推导出了导盘转速控制模型用软测量方法对模型中的负载力矩进行了预测,并利用前馈控制算法来抵消系统的负载力矩扰动.由于软测量模型有一定的误差,故采用了推理控制算法来抵消其不准确部分.最后形成了前馈和推理的复合控制算法作为导盘转速控制系统的控制器.仿真证明了控制系统的准确性、鲁棒性和快速响应性.The guiding disc model is developed by analyzing the hydraulic system which drives the Diescher guiding disc. The load torque which is an important parameter in the model is predicted by the soft measure method. A feed-forward control algorithm is used to reject the load torque disturbance. An inferential control algorithm is also used to compensate the error caused by the soft measure method. The compound control algorithm combines the feed-forward and inferential control algorithm for controlling the speed of the guiding disc. Finally, the accuracy, robustness and fast response of the control system is demonstrated by the simulation.
