An Analytic Algorithm for Constrained GPC in Milling Process
-
摘要: 通过分析性能指标函数和约束条件的特点,提出并证明了两个关于有约束广义预测 控制性质的定理,进而提出了一种解析算法,并将其成功地应用于数控铣削过程.计算机仿真 和切削试验表明,算法效率高且输出性能良好.Abstract: Two physical universal laws about the nature of constrained GPC (Generalized Predictive Control) are proposed and proven through analyzing the characteristics of the cost function and constraints. Then, an analytic algorithm is suggested and successfully applied to the constant force milling control. Computer simulation and cutting test show that the proposed scheme is computationally efficient with good performance.
