Disturbance rejection for nonlinear systems
Tập 5 - Trang 3484-3489 vol.5 - 2002
Tracking or rejection of unknown exogenous signals with known generating dynamics is of major concern in feedback control design. Linear feedback control based on the internal model principle achieves asymptotic performance for linear systems with linear exogenous signal dynamics. This paper presents a control design based on the internal model principle to track or reject nonlinear exogenous sign...... hiện toàn bộ

Distributed diagnosability properties of discrete event systems
Tập 1 - Trang 134-139 vol.1
We present a distributed diagnostics and control architecture for embedded distributed diagnostics. Using this architecture, we (1) propose a distributed diagnostics framework for discrete-event systems based on causal networks; (2) prove system diagnosability results based on component diagnosability; and (3) discuss the tradeoffs involving system diagnosability and communication requirements.

Anti-windup for local stability of unstable plants
Tập 1 - Trang 645-650 vol.1
We consider the problem of anti-windup compensation based on coprime factorizations, for unstable plants with an input saturation nonlinearity. Firstly, we show that the behaviour of the compensated system is related to the behaviour of a simple linear system in feedback with a deadzone nonlinearity. We then state a local stability result which applies to such systems, and state under what conditi...... hiện toàn bộ

On optimal controls for a general mathematical model for chemotherapy of HIV
Tập 5 - Trang 3454-3459 vol.5 - 2002
We describe a class of optimal control problems which arise as mathematical models for biological systems in the chemotherapy of diseases which have a strong cell proliferation aspect such as cancer or AIDS. Although individually these problems are very different in their specifics, yet due to. the underlying mechanisms of cell dynamics, they also have many aspects in common and can be put into on...... hiện toàn bộ

Nonlinear MPC for optimization of recombinant Zymomonas mobilis fed-batch fermentation
Tập 4 - Trang 2879-2884 vol.4 - 2002
Presents the development of an unstructured kinetic model incorporating the differing degrees of product and substrate inhibition on kinetic rates of alcohol fermentation by recombinant Zymomonas mobilis for growth on two substrates. Product inhibition was observed to begin to affect the specific growth rate at 20 g/L and specific productivity at about 35-40 g/L. Additionally, a mechanism for the ...... hiện toàn bộ

Optimal control of HIV infection with a continuously-mutating viral population
Tập 5 - Trang 4033-4038 vol.5 - 2002
There has been much discussion in recent years devoted to determining the optimal methodology for administering anti-viral medication therapies to fight HIV infection. There are many reasons to seek such an optimal therapy, including the minimization of drug toxicity and monetary cost. However, there is increasing recognition that exposure to many anti-HIV medications produces extremely rapid chan...... hiện toàn bộ

H/sub /spl infin// controller design for discrete-time fuzzy systems using fuzzy weighting-dependent Lyapunov functions
Tập 4 - Trang 3252-3257 vol.4 - 2002
For discrete-time Takagi-Sugeno (TS) fuzzy systems, we propose an H/sub /spl infin// state-feedback fuzzy controller associated with a fuzzy weighting-dependent Lyapunov function. In terms of parameterized linear matrix inequalities (PLMIs), the controller employs not only the current-time but also one-step-past information on the time-varying fuzzy weighting functions. Appropriately selecting the...... hiện toàn bộ

Current harmonic detection for induction motor speed sensorless control using fast orthogonal search
Tập 4 - Trang 3088-3092 vol.4 - 2002
This paper describes the design of an improved method of detection of harmonic current components in AC machines. A fully digital implementation of the speed estimator requires the use of DSP routines to perform a spectral analysis of the sampled current waveform and extract harmonic information. Conventional methods using Fast Fourier Transforms (FFTs) are limited by the frequency resolution and ...... hiện toàn bộ

Inner approximations of domains of attraction for constrained continuous time linear systems
Tập 2 - Trang 1216-1221 vol.2 - 2002
When asymptotically stabilizing a system under constraints, the objective is to find the maximal domain of attraction contained in the constraint set. In this paper, we show that if S is a domain of attraction for the exponential discretization of a continous-time system, S scaled by an appropriately defined factor is a domain of attraction for the continuous-time system and arbitrarily well appro...... hiện toàn bộ

Efficient output feedback nonlinear model predictive control
Tập 6 - Trang 4752-4757 vol.6 - 2002
We investigate the efficient implementation of continuous time output feedback nonlinear model predictive control (NMPC) using a moving horizon observer (MHE) for state estimation. For this purpose we briefly review some aspects of MHE and some results on the computationally efficient implementation of nonlinear model predictive control. For the MHE we outline how an efficient dynamic optimization...... hiện toàn bộ
