Product returns from market to the manufacturer can happen because of the motivation to capture the value content of the product after use or the obligation from legislation and the environmental concerns. A manufacturing system capable of integrating both the manufacturing and remanufacturing activities can help the recovery of value content in the products after the end of product’s use life....

The basic vector quantization (VQ) technique employed in video coding belongs to the category of predictive vector quantization (PVQ), as it involves quantization of the (motion compensated) frame prediction error. It is well known that the design of PVQ suffers from fundamental difficulties, due to the prediction loop, which have an impact on the convergence and the stability of the design pro...

This paper presents a Closed Loop Input Error (CLIE) approach for on-line parametric estimation of a continuous-time model of a DC servomechanism functioning in closed loop. A standard Proportional Derivative (PD) position controller stabilizes the loop without requiring knowledge on the servomechanism parameters. The analysis of the identification algorithm takes into account the control law e...

The proper measure of closed-loop performance variation in the presence of modelplant mismatch is discussed in this paper. A generalized closed-loop error transfer function, which is a special representation of the dual Youla parameter and has a close relationship with the pointwise ν -gap metric, is proposed as the suitable means of representing closedloop performance variation in case of plan...

In this paper, dynamic equations of motion of a 5 DoF robot manipulator including mechanical arms with revolute joints and their electrical actuators are considered. The application of integrator backstepping technique for trajectory tracking in presence of parameters of uncertainty and disturbance is studied. The advantage of this control technique is that it imposes the desired properties of ...

Input shaping is a vibration control technique that operates by filtering reference commands so that the modified (or shaped) command does not excite the system’s natural frequencies. Usually, input shaping is limited to a filtering operation outside of any feedback loops. However, this implementation prevents input shaping from effecting some vital control applications including disturbance re...

This paper focuses on the problem of computing a control law which maximizes (in a sub-optimal sense) the delay of the closed-loop system for a class of linear systems with delayed input. The delay is assumed to be a continuous bounded time-varying function. The analysis is given using two diierent approaches: a Razumikhin based method and a frequency-ltering based method.

The adaptive stabilization scheme based on tuning function for stochastic nonlinear systems with stochastic integral input-to-state stability SiISS inverse dynamics is investigated. By combining the stochastic LaSalle theorem and small-gain type conditions on SiISS, an adaptive output feedback controller is constructively designed. It is shown that all the closed-loop signals are bounded almost...
