TLDR
In this article, a design procedure is introduced which incorporates loop shaping methods to obtain performance/robust stability tradeoffs, and a particular H/sub infinity / optimization problem to guarantee closed-loop stability and a level of robust stability at all frequencies.Abstract:
A design procedure is introduced which incorporates loop shaping methods to obtain performance/robust stability tradeoffs, and a particular H/sub infinity / optimization problem to guarantee closed-loop stability and a level of robust stability at all frequencies. Theoretical justification of this technique is given, and the effect of loop shaping on closed-loop behavior is examined. The procedure is illustrated in a controller design for a flexible space platform. >read more

Robust damping control of power systems with FACTS
TL;DR: In this article, a novel BMI-based methodology is proposed for the design of robust FACTS damping controllers, which is capable of managing multiple control objectives under several preselected operating points which could guarantee controller robustness in a broader range.

Hybrid vibration control of offshore wind turbines under multiple external excitations
TL;DR: The results revealed that the HMD control system can better reduce the tower-top displacement as compared to the passive TMD system before and during earthquakes, albeit at the expense of high input control power and large TMD displacements.

Design of Anti-Windup and Bumpless Transfer Controller with Application to Nonlinear Boiler Systems
Young-Sam Lee,Oh-Kyu Kwon +1 more
TL;DR: In this article, the authors deal with the full range control problem of non-linear boiler systems subject to actuator constraints, where three operating points are selected to cover the foil operational range of the boiler systems and the linear controller corresponding to each operating point is designed using H∞ LSDP(Loop Shaping Design Procedure).

Multivariable feedback design: Concepts for a classical/modern synthesis
John Doyle,Gunter Stein +1 more
TL;DR: This paper presents a practical design perspective on multivariable feedback control problems and generalizes known single-input, single-output (SISO) statements and constraints of the design problem to multiinput, multioutput (MIMO) cases.

Feedback and optimal sensitivity: Model reference transformations, multiplicative seminorms, and approximate inverses
TL;DR: In this article, the problem of sensitivity reduction by feedback is formulated as an optimization problem and separated from the problems of stabilization, and the feedback schemes obtainable from a given plant are parameterized.
Analysis of feedback systems with structured uncertainties
TL;DR: In this article, a general approach for analysing linear systems with structured uncertainty based on a new generalised spectral theory for matrices is introduced, which naturally extend techniques based on singular values and eliminate their most serious difficulties.
