Robust control of feedback linearizable system with the parameter uncertainty and input constraint

SICE 2001. Proceedings of the 40th SICE Annual Conference. International Session Papers (IEEE Cat. No.01TH8603), 2001

In this paper, a linear matrix inequality (LMI)-based robust combined control method, which is combined model predictive control (MPC) with the feedback linearization (FL), is presented for constrained nonlinear systems with parameter uncertainty. This scheme is designed in the following 3 steps: Polytopic description of nonlinear system with a parameter uncertainty via FL, Mapping of actual input constraint by FL, ...


LQG/LTR control of a two panel space station

Proceedings IEEE Southeastcon '92, 1992

The authors design a multivariable controller for a two-panel space station using the linear quadratic Gaussian regulator with loop transfer recovery (LQG/LTR) methodology. The controller was simulated and its performance and stability robustness were evaluated. The simulation results are presented and discussed. The compensated plant was stable, responded quickly to disturbances, and was robust to parameter variations. It was found ...


Improved delay-dependent stability criteria for linear systems with time-varying delay

2009 IEEE International Conference on Intelligent Computing and Intelligent Systems, 2009

This paper is concerned with the delay-dependent stability and robust stability for uncertain systems with time-varying delay. Through constructing a general form of Lyapunov-Krasovskii functional, and using slack matrices and the convex combination condition in the calculation, the delay-dependent stability criteria are derived in terms of linear matrix inequalities without applying any bounding techniques. Numerical examples are given to illustrate ...

Student Conference on Research and Development, 2002

A proportional-integral sliding mode control is proposed for a system with mismatch uncertainties. The proposed controller is able to improve the chattering phenomenon. A simulation study for a numerical example is given to illustrate the effectiveness of this control design.

  • Robust control of feedback linearizable system with the parameter uncertainty and input constraint

    In this paper, a linear matrix inequality (LMI)-based robust combined control method, which is combined model predictive control (MPC) with the feedback linearization (FL), is presented for constrained nonlinear systems with parameter uncertainty. This scheme is designed in the following 3 steps: Polytopic description of nonlinear system with a parameter uncertainty via FL, Mapping of actual input constraint by FL, Optimization of the constrained MPC problem based on LMI. To verify the performance and usefulness of the control method proposed in this paper, some simulations with application to a flexible single link manipulator are performed.

    The authors design a multivariable controller for a two-panel space station using the linear quadratic Gaussian regulator with loop transfer recovery (LQG/LTR) methodology.

The compensated plant was stable, responded quickly to disturbances, and was robust to parameter variations. It was found that the LQG/LTR controller proved to be effective in achieving the control objectives.<>

  • Improved delay-dependent stability criteria for linear systems with time-varying delay

    This paper is concerned with the delay-dependent stability and robust stability for uncertain systems with time-varying delay. Through constructing a general form of Lyapunov-Krasovskii functional, and using slack matrices and the convex combination condition in the calculation, the delay-dependent stability criteria are derived in terms of linear matrix inequalities without applying any bounding techniques. Numerical examples are given to illustrate the improvement on the conservatism of the delay bound over some existing results.

  • Robust H∞filtering of fuzzy systems with time varying discrete and ditributed delays

    This paper is concerned with robust Hinfinfiltering for uncertain fuzzy time- delay systems with time varying discrete and distributed delays. Robust filtering conditions and a design method of robust Hinfinfilter are given. The time-delay is assumed to be tune varying. The parameter uncertainties that come into the system are time varying and describe identification error between a real system and its mathematical model. Our approach employs a Lyapunov-Krasovskii functional combined with the parameterized model transformation method and the generalized free weighting matrix method. This generalization leads to a generalized robust Hinfinfiltering condition that is given in terms of linear matrix inequalities. Moreover, based on such a condition, a robust Hinfinfiltering method for uncertain fuzzy systems with time-delays is given. A numerical example is given to illustrate our robust Hinfinfiltering methods.

  • Influence of parameter uncertainties on the performance of some induction actuator indirect field oriented control schemes

    The aim of this paper is to compare the performance of two indirect field oriented control schemes. In the first one, the Park components of the stator currents are controlled by two PI regulators, and in the second one, these currents are not directly controlled and there is no current measurement. It is shown that the sensitivity of the flux control to parameter uncertainties is generally smaller in the control scheme without current controllers than in the control scheme with current PI controllers, in spite of the fact the latter offers a more precise current control. It is also shown that the control scheme without current measurement allows to develop a fully digital implementation on low cost microprocessors. Experiments on a laboratory prototype confirm the good performance of this simplified control scheme.<>

  • Resilient Filtering for Uncertain Systems with Markov Jump Parameters

    The design problem of resilient filter is studied for a class of uncertain Markov jump systems with norm-bounded unknown inputs. It's formulated as the H∞-filtering problem while considering the resilient disturbance of filter parameters. In the precondition of the systems' asymptotically stable, a sufficient condition for the solvability of the H∞-filtering problem and the resilient filter design approach are presented and proved by proper Lyapunov function and linear matrix inequalities. The design problem of the filter is described as an optimization one. Simulation results demonstrate the validity of the proposed approach.

  • Fuzzy neural networks for control of uncertain systems with time delays

    This paper addresses the problem of control of the uncertain systems with time delays. Using fuzzy logic control and artificial neural network methodologies, the paper presents a self-learning fuzzy neural control scheme for general uncertain processes. In this scheme, a neural network compensator is designed instead of the classical Smith predictor for attenuating the adverse effects of time delays of the uncertain systems. The scheme has been used in control of welding pool dynamics of an arc welding process, experimental results show the control scheme to be viable.

  • Synthesis of greatest linear feedback for timed-event graphs in dioid

    This paper deals with the synthesis of greatest linear causal feedback for discrete-event systems whose behavior is described in dioid. Such a feedback delays as far as possible the input of the system while keeping the same transfer relation between the input and the output. When a feedback exists in the system, the authors show how to compute a greater one without decreasing the system's performance.
