摘要

提出了一种分析混合伺服控制系统性能的设计工具——混合灵敏度函数。用计算机对连续时间系统进行控制，并将D/A(数字/模拟)单元建模为理想的零阶保持函数，从而得到混合控制系统。引入的量是纯离散时间灵敏度函数的泛化，它的缺点是不能给出采样时刻之间的性能信息。

The hybrid sensitivity function-a design tool for sampled data control systems

A design tool, the hybrid sensitivity function, for analyzing the performance of a hybrid servo control system is proposed. A hybrid control system is obtained when a continuous-time system is controlled with a computer and when the D/A (digital/analog) unit is modeled as an ideal zero-order hold function. The introduced quantity is a generalization of the pure discrete time sensitivity function, which suffers from the shortcoming that it gives no information about performance between the sampling instants.<>
