Abstract :
A linear control system with two variable parameters is considered in this paper. Identification of the state of the basic system is achieved by a high frequency sinusoidal test signal. The magnitude and phase angle of the perturbed output signal are used in two adaptive loops to detect changes in system gain and the location of a nondominant pole. A simple approach to the prediction of interloop coupling is presented. The results of simulating this adaptive system on an analog computer are given.
