in paper (2004) chang studied an inventory model under a situation in which the supplier provides the purchaser with a permissible delay of payments if the purchaser orders a large quantity. tripathi (2011) also studied an inventory model with time dependent demand rate under which the supplier provides the purchaser with a permissible delay in payments. this paper is motivated by chang (2004) ...

In this study, we propose an advanced sliding mode control (SMC) technique for plants with time delays. In control engineering, the presence of time delays in a control system may cause it to become unstable. Furthermore, SMC cannot control systems having time delays. To solve this problem, we introduce a simple plant predictor to the SMC method. Therefore, our proposed method is designed easil...

in this paper, a new t-s fuzzy hyperbolic delay model for a class of nonlinear systems with time-varying delay, is presented to address the problems of stability analysis and feedback control. fuzzy controller is designed based on the parallel distributed compensation (pdc), and with a new lyapunov function, delay dependent asymptotic stability conditions of the closed-loop system are derived v...

In [1], it was shown that a regular sliding-mode controller is diÆcult to be used in bilateral teleoperation systems with varying time delay in that its nonlinear gain should be set based on the worst time delay. As an alternative to the regular sliding-mode controller, a modi ed sliding-mode controller was proposed to compensate the varying time delay and to guarantee its nonlinear gain to be ...

This paper addresses the estimation of time delay between two spatially separated noisy signals by system identification modeling with the input and output corrupted by additive white Gaussian noise. The proposed method is based on a modified adaptive Butler-Cantoni equalizer that decouples noise variance estimation from channel estimation. The bias in time delay estimates that is induced by in...

Fault tolerant control for uncertain systems with time varying state-delay is studied in this paper. Based on sliding mode controller design, a fault tolerant control method is proposed. By means of the feasibility of some linear matrix inequalities (LMIs), delay dependent sufficient condition is derived for the existence of a linear sliding surface which guarantees quadratic stability of the r...
