    Aspects Regarding Fly Control of Quadcopter
    (2016-09-14) Kuantama, Endrowednes; Tarca, Ioan; Tarca, Radu; Craciun, Dan
    Quadcopter is one of Unmanned Aerial Vehicle (UAV) which has two pairs of identical fixed pitched rotor propellers. It can fly autonomously based on pre-programmed flight or manually controlled by a remote, and every movement achieved by varying the speed of each rotor independently. The orientation of quadcopter axes relative to a reference line and its direction of motion are known as attitude. Fly control factors are affected by attitude determination which can be calculated from 3 possible angles using combined measurement. Gyroscope and accelerometer are primary sensors to control quadcopter attitude, but magnetometer sensor and GPS also used to enhance the stability during flight. This paper will focus on details of function and mathematical formula of every factor regarding fly control and comparative data of 2 types of orientation sensor used in this system.

    Determination of the Calibration Equation for FBG Temperature Sensors
    (2021-12-30) Moldovan, Ovidiu Gheorghe; Moldovan, Alin Octavian; Tarca, Radu Catalin; Craciun, Dan
    This paper presents a brief introduction to FBG sensor technology and its applications. Then the procedure for determining the sensor calibration equations is presented. These equations are determined for each individual sensor and are necessary to perform the trans-oceanographic measurement of the FBG sensor's wavelength variation in the measured parameter.
