—In this paper, we develop linear fixed-order (i.e., full-and reduced order) pressure rise feedback dynamic compensators for axial flow compressors with throttle valve actuation. Unlike the nonlinear static controllers proposed in the literature possessing gain at all frequencies, the proposed dynamic compensators explicitly account for compressor(More)
A general framework for the feedback interconnection of passive nonlinear s stems is used to investigate the effectiveness of modi&ing positive-real LQG compensators with nonlinearities to enhance disturbance rejection and energy dissipation. The primary purpose of the nonlinear modifications is to spread the spectrum of the compen-sator states, and thereby(More)

In this paper we explore the applicability of the implicit small-gain guaranteed cost bound for controller synthesis. For #exibility in controller synthesis, we adopt the approach of "xed-structure controller design which allows consideration of arbitrary controller structures, including order, internal structure, and decentralization. A numerical example(More)
This paper considers "xed-structure H-optimal relative degree two controller synthesis. The problem is presented in a decentralized static output feedback framework developed for "xed-order (i.e., full-and reduced-order) dynamic controller synthesis. A quasi-Newton/continuation algorithm is used to compute solutions to the necessary conditions. To(More)
