Abstract :
Simple stability bounds for closed-loop robustness in the presence of modelling errors are presented in terms of the steady-state gain of the model. The effects of user-specified prefilters upon these bounds are discussed, leading to guidelines for selection of the filters. This allows commissioning of the adaptive controller to be done on the basis of the robustness of the nominal closed loop to modelling errors, based only upon the estimated model and the particular control strategy to be employed
