Allowed gain errors for iterative modelling and controller design
Abstract
The automated design scheme called exploratory modelling for controller optimization (EMCO) isre-examined to obtain simple robust controllers for complex plantdynamics. The allowable gain error (AGE) function is revised to quantify a frequency dependent bound of model gain errors which allow for both robust servo performance and the requiredstability robustness margin to be maintained. AGE lends itself toiterative modelling and controller redesign and the resultingscheme is outlined. It is proven that control has synergistic interaction with system identification of the plant model.
