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...

Automated control systems play an important part in many industrial domains and the medium used for communication between devices in these systems is in transition from wired to wireless for cost reasons. Control systems have strict requirements on delay, throughput, and reliability, that vary with time during operation. Addressing these requirements requires predictable and robust protocols to...

This paper considers stability problem for inputdelayed systems for both constant and time-varying delay case. A new composite state-derivative control law is introduced, in which, a composition of the state variables and their derivatives appear in control law. By this means, the resulting closed-loop system becomes a particular time-delay system of neutral type. The significant specification ...

In this note we give a definition of semiinfinite cohomology for Tate Lie algebras using the language of differential graded Lie algebroids with curvature (CDG Lie algebroids). 2000 Math. Subj. Class. 17-XX.

This paper discusses a method of modeling individual differences in cognitive control by developing models that differ in control structure. Such a strategy for modeling behavior is necessitated when tasks are complex and individual differences in performance vary on many measures of performance. For these tasks, merely adjusting a parameter to fit various groups of subjects may be impractical ...

This paper describes a set of delay-dependent IQC stability conditions for time-delay uncertainty. The IQC’s are linearly parameterized in terms of a pair of rational stability multipliers, each active over one of a pair of complementary frequency intervals. Using the finite-frequency positive real lemma, each of these finite-frequency IQC conditions are shown to be equivalent to a frequency-in...

This work presents a theoretical framework for the safety-critical control of time delay systems. The theory barrier functions, that provides formal safety guarantees delay-free systems, is extended to systems with state delay. notion functionals introduced, attain by enforcing forward invariance safe sets defined in infinite dimensional space. proposed able handle multiple delays and distribut...
