Abstract:

A Nyquist-like stability criterion in conjunction with a simple substitution is utilized to establish convergence properties of linear timevarying systems. The results obtained are applied to a model-referenconic circuits.

The results obtained are applied to a model-reference adaptive control system, and an allowable range of process gain variation is established for which system convergence within a specified time interval is guaranteed. The relationships obtained for the model-reference adaptive control system permit a complete design of the system. Author
