Crane payloads are frequently subject to oscillations induced through movement and external disturbances. These oscillations degrade performance and can be dangerous. Input shaping is an effective method to move cranes without creating oscillation, however it is not effective on initial swing. This paper develops a feedback control system, with two operation modes based on input shaping, that a...

We investigate the constant amplitude nature of several time-optimal input shaping designs for controlling exible structures. We rst discuss the equivalence of the time-optimal zero-vibration shaper with the traditional time-optimal control problem. Then we show that several robust time-optimal shaper designs for exible systems are equivalent to the time-optimal controls for diierent systems. T...

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

a phase-locked loop (pll) based frequency synthesizer is an important circuit that is used in many applications, especially in communication systems such as ethernet receivers, disk drive read/write channels, digital mobile receivers, high-speed memory interfaces, system clock recovery and wireless communication system. other than requiring good signal purity such as low phase noise and low spu...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

This paper is has addressed the Single Flexible Link Robot. The dynamical model is derived using Euler-Lagrange equation and then a proper controller is designed to suppress a  vibration based-on Input-Shaping (IS) method. But, IS control method is an open loop strategy. Due to the weakness of open loop control systems, a closed loop IS control system is proposed. The achieved closed loop c...

the present study was conducted to investigate the effect of implicit focus on form through input flooding and the effect of noticing, explicit focus on form on linguistic accuracy. to fulfill the purpose of the study, 86 iranian pre-intermediate efl learners of one of the language institutes were chosen by means of administering ket as the homogeneity test. these learners were pretested throug...

To achieve the highest level performance with computer controlled machines, the flexibility of the system must be taken into account. Feedforward methods are often the most desirable means of eliminating vibration. The fastest motions can be obtained by using the timeoptimal flexible-body command. These commands depend on the system parameters, actuator limits, and the desired motion. Input sha...
