Abstract: In many recent applications, the control engineer is faced with the problem of controlling a linear system modeled by a transfer function of high or infinite order. In a majority of these ...

Abstract: Compensator design results are compared for the circle and Popov criteria, both of which are sufficiency conditions for absolute stability of nonlinear control systems. Analog simulation studies ...

Abstract: The problem of synthesizing a controller to yield a specified overall system phase margin requires specification of both the time constant (or constants) and the gain of the controller, but ...

Abstract: This paper deals with a design approach to the synthesis of controllers for nonlinear control systems. The method proposed herein uses the frequency domain circle condition as a sufficiency ...

Abstract: The well-known modal control technique has been reviewed and a new computational approach been developed. Unlike other methods, this approach is both nonrecursive and independent of the relative ...

Abstract: A class of dynamical systems containing uncertain elements and subject to uncertain inputs is considered. The plant parameter uncertainties are assumed to be “unknown-but-bounded.” Design criteria ...
