This paper deals with the problem of angle-of-attack modulation with the aim of enhancing transient performance of entry guidance during bank reversals, while compensating adverse effects of fast time-varying transient disturbances. An extended single-input/single-output system is developed in the velocity domain by means of a dynamic extension technique, and explicitly captures the trajectory ...

This paper presents a robust mixed-sensitivity H1 controller design via loop-shaping methodology for a class of multiple-input multiple-output (MIMO) uncertain nonlinear systems. In order to design this controller, the nonlinear plant is first modeled as several linear subsystems by Takagi and Sugeno’s (T–S) fuzzy approach. Both loop-shaping methodology and mixed-sensitivity problem are then in...

This paper investigates the decentralized output-tracking problem for a class of high-order stochastic nonlinear systems (SNSs). Compared with existing results, we consider more practical and general systems, i.e., system is large-scale linearization parts may have unstable modes. An output-feedback tracking controller designed based on high-gain homogeneous domination technique. By using advan...

The propagation of error in numerical solutions of the compressible Navier-Stokes equations is examined using linearized, and adjoint linearized versions of the discrete flow solver. With the forward linearization it is possible, given a measure of the local residual error in the field, to obtain estimates of global solution error. This allows for example the computation of error estimates on p...

We present a method for trajectory planning and control of planar robots with a passive rotational last joint. These underactuated mechanical systems, which are subject to nonholonomic second-order constraints, are shown to be fully linearized and input-output decoupled by means of a nonlinear dynamic feedback. This objective is achieved in a unified framework, both in the presence or absence o...

We investigate the spatial behavior of nonclassical light produced by type I second-harmonic generation in the traveling-wave configuration. An input-output transformation for the system of fundamental and secondharmonic field is derived in the framework of a linearization approach and used to investigate the properties of an optical system, which consists of a crystal with a quadratic nonlinea...

This paper presents the technical aspects, theoretical analysis, and comparisons of two new permanent magnet synchronous generator (PMSG) grid-interfaced models named PMSG boost and PMSG rectifierinverter. The exact feedback linearization (EFL) control scheme is used for the effective design and stability analysis of the aforementioned models. The complexity of the EFL control laws is discussed...

This paper investigates the stabilization problem by means of a static output feedback control for positive systems with/without interval uncertainties. The designed closed-loop system is ensured to be positive and stable with a prescribed decay rate. Necessary and sufficient conditions for the existence of such controllers are established in terms of linear matrix inequalities together with a ...

In this study, the rate equation analysis of a BH-laser diode was performed for output carrier density (No) using the zero-degree solution of the Volterra series. The carrier rate equation of the laser diode was analyzed in terms of input carrier density (Ni) and output carrier density modeling (Ni − No) , with respect to the DC current (Io) . The polynomial root, which is obtained from the zer...
