In this paper, a new decentralized adaptive control with modified Minimal Controller Synthesis MCS is proposed to position the beam of the Twin Rotor Multi-input multi-output System (TRMS) at the desired positions quickly and accurately. A new hyperstability based adaptive control technique, called decentralized Error-based minimal controller synthesis with integral action (DEr-MCSI), is develo...

Abstract In this paper, a hybrid mass damper (HMD) and its hyperstability thanks to power flow approach are studied. The HMD proposed combines an active control system with optimal passive device. initial is electromagnetic Tuned Mass Damper (TMD) the law modified velocity feedback phase compensator. resulting controller theoretically hyperstable ensures fail-safe behavior. Experiments performe...

We consider Jackson queueing networks with finite buffer constraints (JQN) and analyze the efficiency of sampling from their stationary distribution. In the context of exact sampling, the monotonicity structure of JQNs ensures that such efficiency is of the order of the coupling time (or meeting time) of two extremal sample paths. In the context of approximate sampling, it is given by the mixin...

In recent years, many efforts have been made to isolate enzymes from extremophilic organisms in the hope to unravel the structural basis for hyperstability and to obtain hyperstable biocatalysts. Here we show how a moderately stable enzyme (a thermolysin-like protease from Bacillus stearothermophilus, TLP-ste) can be made hyperstable by a limited number of mutations. The mutational strategy inc...
