The paper describes a method of realizing non-interacting control for a motor-alternator set so that an adjustment of the alternator output voltage can be made without varying the frequency and vice versa. While the parameters of the linear model of the motor-alternator set are constant for small signals, they vary when the operating point changes and adaptive control is used to maintain non-interaction. A real model following control law and the instrumental variable method of parameter estimation are the two main parts of the adaptive scheme. A description of the experimental work, consiting of the construction of transducers and the implementation of the controller on a hybrid computer, is also given. Results obtained at two different operating points show that non-interaction was achieved after adaptation.
