ABSTRACT
Dynamic errors, an important aspect in digital simulation of dynamic systems, are introduced. Instead of focusing on truncation errors, the simulationist may be more concerned with errors in dynamic response, a yardstick of simulation accuracy involving comparisons of transient and sinusoidal responses of continuous-time and discrete-time models. The connection between digital simulation and discrete-time systems is further illustrated by exploring the subject of stability in both arenas. Stiff systems, initially introduced in Chapter 6, are once again considered. Multirate integration schemes are presented as an alternative to the use of stiff integrators for the case where the overall system can be decomposed into several interconnected subsystems operating at different speeds.
