This paper investigates the stabilizability of positive time-delay system. The nonnegative constraint makes the design of a control law different from a general system. Firstly, a method to calculate the L-1 gain of a positive time delay system is presented. Then, the design of a state feedbackcontroller and a high gain observer is presented by taking full advantage of the characteristics of the positiveness of the system. Finally, the observer and feedbackcontroller are combined to stabilize the system and improve dynamic performance. A numerical example illustrates the provided method is effective.

Reference tracking problem for MIMO Lipschitz nonlinear systems is examined here. Presently a vast literature exists on observer design of unforced systems containing Lipschitz nonlinearities. However, these existing results cannot be readily extended for controller design containing reference tracking ability. Here a Linear State Variable feedback (LSVF) controller is designed for MIMO Lipschitz nonlinear systems with norm-bounded parametric uncertainties using the concept of input to state stability Lyapunov functions. The whole problem is cast into a framework of Linear Matrix Inequalities, to exploit its numerical capabilities. Analytical proofs are supplemented with simulation examples, which show certain advantages over existing results. Apart from state feedback, observer-based output feedback is also considered for controller design.

This paper focuses on observer and observer-based robust H-infinity feedbackcontroller design for positive delta operator systems with time-delays. First of all, a positive observer is designed to estimate the states of the proposed positive system, which is a Luenberguer-type and ensures the estimation to be nonnegative at any time. Moreover, an observer-based robust H-infinity feedback control problem is considered for further study. New sufficient conditions for the existence of the desired controller are derived as LMIs such that the resulting closed-loop system is positive and asymptotically stable simultaneously. Finally, a simulation example is provided to demonstrate the effectiveness of the proposed approach.

H-infinity control is studied for a class of uncertain linear systems when the uncertainty is assumed to exist in the state matrix. A decentralized control scheme with two observer-based feedback controllers is developed for such a class of uncertain linear systems with two control channels. The gains of the observer-based feedback controllers can be computed from the positive-definite solutions of the two Riccati-like algebraic equations with some tuning freedom. The resulting closed-loop system provides guaranteed stability and H-infinity-norm bounded performance in the presence of parameter uncertainty.
