Automatic Step-size Control in Wave Digital Simulation Using Passive Numerical Integration Methods

Summary Wave digital filter principles can be applied to the numerical solution of many kinds of differential equations. It has been shown that, by merging the wave digital concept with Runge-Kutta methods, algorithms of high accuracy can be found which are passive and hence possess a lot of desirable numerical stability properties. In this paper, we will discuss the applicability of step-size control within this framework.
