Youeyun Jung, Hyochoong Bang(Korea Advanced Institute of Science and Technology, Korea, Republic of ), Dongjin Lee(Hanseo University, Korea, Republic of ) |
The robust marker tracking and relative navigation algorithms are presented for precise UAV vision-based autonomous landing. To recognize the marker in close-range, the concentric circles are adopted as the marker with ellipse fitting algorithm based on Direct Least Square. We assume that IMU provides vehicle’s attitude and altitude so that we consider GPS-denied situation. Also multiple ellipses are used to estimate its center pixel coordinate, and the filter makes UAV land more accurately.what is the generic name for bystolic open bystolic savings card program cialis dosage for enlarged go cialis dosage forum type 2 diabetes signs diabetes treatment type 2 diabetes signs go diabetes treatment cialis coupon discounts site buy generic cialis cialis discount coupons go cialis price check cialis discount coupons go cialis price check lilly cialis coupons click free discount prescription cards prescription discounts cards drug coupons coupons for cialis 2016 prescription discounts cards read coupons for cialis 2016 prescription discounts cards read coupons for cialis 2016 |

One Chip Controller Design for Actuator's Power Driving Circuit using FPGA |
|
Minho Yoon, Taesam Kang(Konkuk university, Korea, Republic of ) |
The piezoelectric material is being used widely for actuators due to its large power density with simple structure. It can generate larger force than the conventional actuators with same size. Furthermore, response time of piezo actuators is very short, and thus, it can be used for very fast system applications with compact size. To control the piezoelectric actuator, we developed one-chip controller that can handle analog and digital signals simultaneously using FPGA technology. In this paper we introduce the design of one chip controller using mixed signal FPGA, SmartFusion device.bystolic generic link bystolic coupons for free prescription discounts cards read coupons for cialis 2016 prescription discounts cards read coupons for cialis 2016 coupons for cialis printable click new prescription coupons aidamar open aida angebote |

Three-Dimensional Impact Angle Control Guidance Law Using Quaternion |
|
Kuk-Kwon Park, Sang-Sup Park, Chang-Kyung Ryoo(Inha University, Korea, Republic of ) |
This paper suggests the impact angle control guidance law defined in three dimensional space. The formal impact angle control guidance laws were described as biased PN guidance law which consisted of PN and biased term. Now the proposed impact angle control guidance law is composed of the PN term extended from two-dimensional planes to three-dimensional spaces and the biased term using rotation angle and Euler axis of quaternion to express the desired impact angles control. We investigate the three-dimensional impact angle control guidance law via numerical simulations using dynamics model.type 2 diabetes signs diabetes treatment type 2 diabetes signs diabetes treatment cialis discount coupons go cialis price check ciprofloxacin go cipromed |

In this paper, the direction integrated pedestrian motion classification method on the omnidirectional treadmill is proposed based on a navigation algorithm. The virtual reality technology is widely applied to a military training in recent years since previous drill conducted outside is relatively cost and time inefficient. Among several roles in training system, motion recognition including direction determination is essential, but the classification result by a classifier only becomes a problem. In order to improve the classification accuracy, navigational error is obtained using an EKF-ZUPTcialis discount coupons go cialis price check coupons for cialis printable click new prescription coupons ciprofloxacin go cipromed |

Satellite Celestial Navigation using Star-tracker and Earth Sensor |
|
Hyun-Seung Kim, Ju-Hyeon Hong, Woo-Sung Park, Chang-Kyung Ryoo(Inha University, Korea, Republic of ) |
In this paper, a satellite celestial navigation which estimates the satellite position on the orbit is proposed. It consists attitude sensor with star-tracker and earth sensor. The proposed algorithm is based on that the position on surface is determined in case of having different observation angle for each star at zenith. Algorithm performance is examined via simulation considering error parameters of attitude sensor. The proposed satellite celestial navigation algorithm estimates satellite position on the orbit in real time, since it obtains the observation angle and altitude directly.prescription discounts cards read coupons for cialis 2016 |

Guidance Algorithm for Satisfying Terminal Speed and Impact Angle Constraints with The Neural Network Technique |
|
Kyujin Moon, Sang-Sup Park, Chang-Kyung Ryoo(Inha University, Korea, Republic of ) |
It is important to control a missile to hit a target with the terminal speed and impact angle constraints. In this paper, we propose a guidance algorithm to satisfy the terminal constraints. The algorithm includes a neural network for learning data set comprised of initial parameters at the terminal homing phase and the corresponding terminal speed. The neural network calculates the flight path angle to meet the terminal speed constraint with the initial parameters and control the missile. After that, the missile is guided to the target with the impact angle constraint via IAC law.type 2 diabetes signs diabetes treatment lilly cialis coupons click free discount prescription cards coupons for cialis printable click new prescription coupons |
