广义预测控制算法中参数的选择

Parameter selection in the generalized predictive control algorithm

分析广义预测控制算法中若干参数的选择对系统控制性能的影响;在内模控制结构下利用广义预测控制从对象至闭环特征多项式的系数关系,分析柔化因子α的选取对闭环系统稳定性的影响,给出选取这些参数的一般性原则。

This article analyzes the influence of some parameters selection upon the control performance of system in the generalized predictive control algorithm and the influence of the factor selection upon the stability of closed - loop system in the internal model control structure by using the generalized predictive control coefficient relation from object to closed - loop characteristic polynomial. Universality principle of choosing these parameters is put forward in this article.
