The paper presents the first result on nonholonomic systems enjoying Input to State Stability (ISS) properties. Although it is known that smooth stabilizability implies ISS, the converse is not generally true. This leaves the possibility of non smoothly stabilizable systems being ISS with respect to a particular input, after an appropriate feedback transformation. This is shown to be true for t...

This paper describes the guiding principles, criteria and methodology of the education quality evaluation on master of engineering degree in control engineering of China. The practice of two-year long “point, line and plane” comprehensive evaluation methods (PLPEM) is summarized, which includes the self-evaluation within every university, evaluation on selected universities and evaluation on a ...

To analyze the contribution of each element in a sensory feedback control system, it is necessary to study the system with the feedback loop opened. Some physiological systems have multiple or even unknown sources of feedback, which makes it exceedingly difficult to open the loop. Conversely, it is relatively easy to open the loop on the human eye-movement system. Study of this system should he...

Feedback is used primarily for reducing the effects of the plant uncertainty on the performance of control systems, and as such understanding the following questions is of fundamental importance: How much uncertainty can be dealt with by feedback? What are the limitations of feedback? How does the feedback performance depend quantitatively on the system uncertainty? How can the capability of fe...

This quasi-experimental study set out to examine the effect of peer corrective feedback on feedback givers and receivers in L2 writing. The forms in focus were a/an, the, and the past tense.The study was conducted in an EFL classroom setting with 45 learners of English in three writing classes which served as the feedback givers, receivers, and the control group.  Over four sessions of treatmen...

Homogenous Charge Compression Ignition (HCCI) engines hold promise of high fuel efficiency and low emission levels for future green vehicles. But in contrast to gasoline and diesel engines, HCCI engines suffer from lack of having direct means to initiate combustion. A combustion timing controller with robust tracking performance is the key requirement to leverage HCCI application in production ...

An enhanced displacement feedback structural control procedure is presented for performance-based design in this paper. At first, a comparative study is implemented assessing three most common active control algorithms including state, acceleration, and displacement feedback controls. The advantage of the displacement feedback algorithm for active control of structures against earthquakes is de...
