备注

带有积分环节的双电机伺服系统在实际应用中是十分重要并具有代表性的系统。针对包含积分环节的测控地面站伺服系统,文中提出了一种带有前馈补偿的改进动态矩阵控制(DMC,Dynamic Matrix Control)算法来提高已有PID算法的控制性能。首先,通过重构动态矩阵和移位矩阵来预测带有积分环节系统的未来输出; 其次,当系统中存在扰动时,通过加入前馈补偿来提高响应速度和动态控制性能; 最后,通过一个仿真实例验证了文中所提算法的有效性。

Dual-motor driving systems with integration elements are very important and typical in practical application.In this paper,an improved dynamic matrix control(DMC)algorithm with feed-forward compensation for this kind of systems is presented to improve the control performance of the existing PID algorithm.Firstly,the dynamic matrix and the shift matrix are reconstructed to predict the future output of the system with the integration element; Secondly,the feed-forward compensation is added when the disturbance occurs,to improve response speed and dynamic control performance; Finally,the effectiveness of the presented algorithm is verified through an example.
