以双输入多率采样系统为例,推导出双输入采样周期不等的多率输出误差系统的离散时间状态空间模型,进而得出对应的传递函数模型。论文提出了这类双输入多率采样数据系统的最小二乘迭代辨识算法,仿真例子说明了提出算法的有效性。
The state-space models are derived for multirate output-error systems with two different input sampling periods and further the corresponding transfer functions are obtained.The least-squares-iterative identification algorithm based on the iterative least-squares principle is presented and the simulation results indicate that the proposed algorithm has good performances.
