# Magnitude- and time-scaling of state-variable equations for analog/hybrid computation

@article{Cannon1973MagnitudeAT, title={Magnitude- and time-scaling of state-variable equations for analog/hybrid computation}, author={Michael R. Cannon}, journal={Simulation}, year={1973}, volume={21}, pages={23 - 28} }

The programming of differential equations on an ana log or hybrid computer usually requires that the system be scaled in both magnitude and time to pre vent overloading the amplifiers and to obtain the desired speed of solution. This paper, which is tutorial in nature, presents a systematic matrix method which may be used to scale differential equa tions written in state variable format. The proce dure requires estimates of the maximum values of each computer variable, and the technique is…
