Robust H2 Performance: Guaranteeing Margins for LQG Regulators
نویسنده
چکیده
This paper shows that H 2 (LQG) performance speciications can be combined with struc-tured uncertainty in the system, yielding robustness analysis conditions of the same nature and computational complexity as the corresponding conditions for H 1 performance. These conditions are convex feasibility tests in terms of Linear Matrix Inequalities, and can be proven to be necessary and suucient under the same conditions as in the H 1 case. With these results, the tools of robust control can be viewed as coming full circle to treat the problem where it all began: guaranteeing margins for LQG regulators.

Robust Control System Design via Optimal, Classical and Adaptive Techniques
Linear quadratic gaussian (LQG) optimal control techniques can control linear multivariable systems that are precisely known [1,2]. Within the framework of the design, they achieve a best possible performance. However, if the plant is imprecisely known, actual performance can be intolerably poor. The guaranteed gain and phase margins for the case of the nominal plant may evaporate in the presen...
متن کاملRobust Control and μ analysis of Active Pneumatic Suspension
This paper presents a novel concept of active pneumatic suspension which uses an accumulator, airspring, and smart control system to actuate a variable orifice mechanism which connects the airspring to the accumulator. The main objective is to obtain a linear model for this pneumatic suspension so as to use existing advanced linear control methodologies to ascertain the closed loop performance ...
متن کاملRobust H2 switching gain-scheduled controller design for switched uncertain LPV systems
In this article, a new approach is proposed to design robust switching gain-scheduled dynamic output feedback control for switched uncertain continuous-time linear parameter varying (LPV) systems. The proposed robust switching gain-scheduled controllers are robustly designed so that the stability and H2-gain performance of the switched closed-loop uncertain LPV system can be guaranteed even und...
متن کاملH2 and Mixed-Hz/H, Stable Stabilization
In certain applications the use of stable compensators greatly simplifies controller testing and implementation. Unfortunately, standard LQG theory, as well as mixednorm H2/H, theory, may yield compensators that are unstable. The problem of synthesizing stable stabilizing controllers has been of interest for many years [14], and a variety of techniques have been proposed based on modifications ...
متن کاملAn Exact Solution to General Four-Block Discrete-Time Mixed Problems via Convex Optimization
The mixed H2=H1 control problem can be motivated as a nominal LQG optimal control problem subject to robust stability constraints, expressed in the form of an H1 norm bound. While at the present time there exist efficient methods to solve a modified problem consisting on minimizing an upper bound of the H2 cost subject to the H1 constraint, the original problem remains, to a large extent, still...
