SENSITIVITY CONSIDERATIONS IN CONTINUOUS AND SAMPLED-DATA CONTROL SYSTEMS,
Abstract
Sensitivity is the percentage change in transmission function due to a percentage change in plant parameter. The sensitivity functions of sampled-data control systems are derived and are shown to be similar to the sensitivity functions of continuous control systems. The Bode diagram is used to investigate the sensitivity function in the frequency domain. The sensitivity functions of continuous and sampled-data control systems are shown to have characteristics which depend on the type of the sensitivity function. For frequencies approaching one-half the sampling frequency, the magnitude of the sensitivity functions of sampled-data systems is greater than one. As sampling frequency increases, the poles of a sampled-data system move toward z-1 on the z-plane root-locus diagram. (Author)
