Abstract:

A procedure for the design of a digital controller to compensate a certain class of linear timevarying processes is presented. The process time variation may be rapid compared to the input signals and is assumed to be caused by modulation of a plant with known parameters perhaps also time-varying by a number of correlated random disturbances. The general results are applied through digital computer simulation to an example involving a plant modulated at the input by correlated random noise. The adaptive controller employed to compensate this plant is shown to produce far better performance than a nonadaptive fixed controller which cannot take noise correlation into account. Finally, a method of generating sets of correlated gaussian time series with specified cross-and autocorrelation functions is described. Such a technique is required in the simulation study, as well as having important applications in many other fields. Author
