Robot force control is an important issue for intelligent mobile robotics. The end‐point stiffness of a robot is a key and open problem in the research community. The control strategies are mostly dependent on both the specifications of the task and the environment of the robot. Due to the limited stiffness of the end‐ effector, we may adopt inherent torque t...
Laser diodes, in general, are sensitive to optical feedback, especially with regard maintaining single-frequency operation. Until now, however, the feedback sensitivity of high-power devices such as distributed Bragg reflector (DBR) tapered laser diodes has not been investigated quantitative detail. In this paper, we analyze impact very weak between <mml:math xmlns:mml="http://www.w3.org/1998/M...
Landing is a challenging flight phase for automatic control of fixed-wing aircraft. For unmanned air vehicles in particular, it is imperative that model uncertainty be considered in the control synthesis. These vehicles tend to have limited sensors and instrumentation, yet must achieve good performance in the presence of modelling errors and exogenous inputs such as turbulence. Quantitative Fee...
This paper aims at investigating the problem of Load Frequency Control (LFC) in interconnected power systems in order to obtain robustness against uncertainties. A design method for a robust controller, based on Quantitative Feedback Theory (QFT), has been presented in this paper. For a two-area power system, the simulation results show that the system response with the proposed QFT controller ...
abstract the extent to which teachers’ written corrective feedback (wcf) is conducive to esl learners’ improvement has been discussed since truscott’s claim in 1996. the mentioned debate continues because there has been lots of contrastive research studies with different results. this paper presents the results of a 2-month study of the effectiveness of wcf to 65 low intermediate iranian learne...
In this second report on quantitative methods, I consider the foundational triumvirate that underpins sub-discipline: data, and theory. argue that, although ‘big data’ and, more recently, code’ may have captured limelight, theory is invaluable should not be disregarded. Showcasing integral role of in human geography, identify three kinds useful (old school, enduring conceptual) along way, highl...
The Wisdom of Crowds, an innovative theory described in social science, claims that the aggregate decisions made by a group will often be better than those of its individual members if the four fundamental criteria of this theory are satisfied. This theory used for in clustering problems. Previous researches showed that this theory can significantly increase the stability and performance of...
