摘要
首先利用提升技术，构造出多采样率数字控制系统的线性时不变状态空间模型。在此基础上，讨论多采样率数字控制系统在输出反馈下的极点配置问题。通过引入假象输出，简化了反馈增益阵的术解过程。同时通过预先固定反馈增益阵中的某些元素的方法，使得控制器满足因果约束的要求。最终可以利用求解线性方程组的方法来设计极点配里控制器。
Using lifting techniques, a linear time-invariant state space model of multirate digital control systems is constructed at first. Then the pole assignment of multirate digital control systems under output feedback is discussed. With introduction of fictitious output, the solution of output feedback gain matrix is simplified. On the other hand, by prefixing some elements in the output feedback gain matrix, the casual condition of the controller is automatically satisfied. Finally, the pole assignment controller can be realized by the solution of a set of linear equations.
