Systems that exhibit flexible dynamics are susceptible to vibration caused by changes in the reference command, as well as, from external disturbances. Feedback control is an obvious choice to deal with these vibrations, but in many cases, it is insufficient or difficult to implement. Input shaping has proven beneficial for reducing vibration that is caused by changes in the reference command. ...

In this paper, a robust adaptive actuator failure compensation control scheme is proposed for a class of multi input multi output linear systems with unknown time-varying state delay and in the presence of unknown actuator failures and external disturbance. The adaptive controller structure is designed based on the SPR-Lyapunov approach to achieve the control objective under the specific assump...

1 CHAPTER 1: Strain Imaging of Internal Deformation 4 1.

Index Terms—sliding mode control, uncertainty and disturbance estimation, flexible joint. Abstract—This paper proposes sliding mode control based on uncertainty and disturbance estimator (UDE), for trajectory tracking control of flexible joint robotic system. UDE is used to estimate plant uncertainty and disturbances. The controller does not requires knowledge of plant uncertainty and external ...

the charge transfer (ct) complex formation of benzonitrile as acceptor with the aromatic donors o-, m-, p-xylene and ethylbenzene in ccl4 solutions is investigated by chemical shift measurements relative to an external reference. the equilibrium parameters, q and dad of their weak molecular complexes, as found numerically modified cresswel- allred (c-a) method, is compared with graphically scat...

While consumer behavior and policy researchers have contributed to legislation and legal decisions for reference price advertising, there is hardly any research on how "other" external price information may impact the effects of reference prices and associated semantic cues. These issues are studied with two 3 x 2 x 2 experiments. Results of the first study indicate that consumer evaluations ar...

We examine the effect of reference prices on consumer bidding behavior in interactive pricing mechanisms used in online retailing, e.g., auctions and name-your-own-price. We find significant influences of different reference price concepts on bid values. However, after controlling for internal and external reference prices, sellers only have a moderate ability to affect bid values via the provi...

We address the problem of how to integrate fault-tolerant external and internal clock synchronization. In this paper we propose a new external/internal clock synchronization algorithm which provides both external and internal clock synchronization for as long as a majority of the reference time servers (servers with access to reference time) stay correct. When half or more of the reference time...
