The paper describes a technique for the optimisation of the parameter settings of the excitation controller of a synchronous machine which is suitable for on-site use. The optimisation method is based on an integral squarederror criterion, and involves the use of parameter sensitivity functions to estimate the parameter changes needed to alter system responses to approach some predetermined or desirable form. The computation of the parameter sensitivity functions is achieved by a direct method, which does not demand explicit identification of the controlled system and which yields the sensitivityfunctions of all output variables to all adjustable parameters from the results of a single-step test. The technique may be implemented using a small digital computer. The paper includes the results of simulation studies on unsynchronised and on loaded generators, together with results of micromachine experiments.
