Evaluation of a Possibility of Estimation of Reaction Force of Simple Hydraulic System using Sliding Perturbation Observer |
|
Hyun Cheol Lee, Keum Gang Cha, Min Cheol Lee(Pusan National University, Korea, Republic of ) |
In contaminated area sensors have high risk of malfunction, and human cannot work in this area. Therefore, master and slave system without sensors is needed. The reaction force estimation for hydraulic system is evaluated. Previously, estimation of reaction force using SPO has been applied to electric motor system. However, hydraulic system has different elements which are uncertain parameters such as compressibility and viscous friction from electric system. For this estimation, hydraulic system is modelled by using signal compression method to simplify the system.cialis discount coupons go cialis price check pet prescription discount card codesamples.in prescription drug coupons coupons for cialis printable click new prescription coupons |

Average Consensus of Multi-agent System With Binary-valued Observations |
|
Ximei Wang, Ting Wang, Changbao Xu, Yanlong Zhao(Chinese Academy of Sciences, China) |
This paper considers average consensus problem of a multi-agent system with binary-valued observations. The
information network transfers binary-valued information and the control is a quantity of transportation between neighbors.
We propose a two-scale average consensus algorithm with a constant gain and prove the convergence and convergence rate
of the algorithm. The algorithm is proved to be convergent and
asymptotically efficient, meanwhile, the renewal of agents can lead to average consensus. Finally, simulations illustrate
the effectiveness of the obtained results.new treatment for diabetes dosage for cialis |

Inequality Constrained Kalman Filter for Bearing-Only Target Motion Analysis |
|
jonghoek kim, Taeil Suh, Jonha ryu(agency for defense development, Korea, Republic of ) |
The Bearing-Only Target Motion Analysis (BOTMA) problem is to estimate the position and velocity of a
target using bearing measurements. In this paper, we assume that the observer can access the inequality constraints
imposed on target’s speed, range, or target’s course. For example, one constraint on a target’s range is that it is upper
bounded by the maximum sensing range of the observer. We introduce an inequality constrained TMA, which is to
derive target states satisfying the constraints. We verify the effectiveness of our inequality constrained TMA using
MATLAB simulations.discount prescription drug cards drug coupons new treatment for diabetes dosage for cialis type 2 diabetes signs diabetes treatment cialis coupon discounts site buy generic cialis cialis discount coupons go cialis price check |

This paper proposes a second-order high-speed sliding
mode (SHSM) observer and compares the performance with the recent higher-order sliding mode (HOSM) observer for the problem of sensorless speed estimation in the permanent magnet synchronous
motor (PMSM). In which, a sigmoid function is substituted for the signum function with a variable boundary layer. A SHSM observer is proposed to provide the estimation of back electro motive forces (EMFs) that are treated as unknown inputs in the PMSM model. An accurate speed estimate of PMSM can be algebraically computed with the estimated back EMFs.cialis discount coupons go cialis price check prescription drugs coupon eblogin.com cialis coupons 2015 prescription discounts cards drug coupons coupons for cialis 2016 prescription discounts cards read coupons for cialis 2016 |

Road Profile Modeling by Subspace Identification Methods |
|
semiha turkay(anadolu university, Turkey) |
In this paper, spectral models for the road profiles from road elevation measurements using
nonparametric and subspace identification methods are developed. First, the power spectra of the road profiles are estimated
on a uniform grid of frequencies by averaging and windowing from the measurements. These calculations are
illustrated on the data set obtained from the University of Michigan Transportation Research Institute archives
by computing the Welch spectrum estimates for the left and the right tracks. Then, curve fitting methods by single-slope and two-slope approximations are percialis discount coupons go cialis price check prescription discounts cards read coupons for cialis 2016 coupons for cialis printable click new prescription coupons |

|
Alexander Laray(Far Eastern Federal University, Russian Federation), Dmitry Yukhimets(Institute of automation and control processes, Russian Federation) |
During the synthesis of control systems of movement of various robotic objects the dynamics of their actuators play important role. The dynamics of these actuators affects significantly to the accuracy of the control system. The paper proposes an approach to the identification of the dynamic model of actuators of mobile robots. The feature of the proposed method is to use the method of least mean squares (LMS) to identify the parameters of nonlinear dynamic objects. The results of experimental research for the actuator of the UAV are presented in paper.cialis discount coupons open cialis savings and coupons cialis discount coupons open cialis savings and coupons ciprofloxacin go cipromed |
