Abstract
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
