摘要：
Passivity of systems comprising a continuous time plant and discrete time controller is considered. This topic is motivated by stability considerations arising in the control of robots and force-reflecting human interfaces (''haptic interfaces''). Necessary conditions for passivity are found via a small gain condition, and sufficient conditions are found via an application of Parseval's theorem and a sequence of frequency domain manipulations. An example - implementation of a ''virtual wall'' via a one degree-of-freedom haptic interface - is given and discussed in some detail. (C) 1997 John Wiley & Sons, Inc.
