R69-12 Design Method for Digital Dead Beat Controller

This paper presents an analog computer technique for designing digital dead beat controllers. The method is useful for both linear and nonlinear sampled data systems. It involves the simulation of the open loop system of interest, the generation of appropriate stepwise variable input signals, and the display of the output on a multichannel oscilloscope. The author reports that a typical controller design can be evolved in less than one hour, this time including the setup of the computer, checkout, and the determination of the controller coefficients.
