The Digital Correction Problem in the Hybrid Simulation of Continuous Systems

In this paper, the general and the particular aspects of the digital correction inthe digital-analog hybrid simulation of continuous systems are introduced, and the theoretical property of the digital correction network is deduced. It is pointed out that somefactors must be considered when we choose the digital correction network, for example,realizability, stability, damping and bandwidth. Three methods for choosing the correction network are introduced. Finally, the relationship between the precision of thenetwork and its compatibility is shown with an example.
