This research proposes modelling, simulation and implementation of autonomous unmanned quadrotor prototype based on Matlab Simulink software, and Mission Planner for communicating with APM control board of the quadrotor. The goal is to Control attitude and altitude over a desired trajectory of the Quadrotor using PID control, with high precision and reliability. The mathematical model used for simulation takes into account all differential equations of motion of the quadrotor. A full quadrotor prototype was assembled for real experiments to do a comparison between real and simulated data.

This comparison reveals the reliability and the accuracy of the PID controller and the mathematical model used in Matlab. International Journal of Science and Engineering Applications, Generally, Quadrotor type Unmanned Aerial Vehicles are unstable in nature, so to stabilize it, the controller is used. The gain parameters of the PD controller, the proportional gain Kp and the derivative gain Kd are apply to be stable and good performance. Unmanned aerial vehicles UAV are becoming increasingly common and span a huge range of size and shape. After integrating PD controllers into the systems, quadcopter settling time of roll, pitch and yaw system. Simulations result and comparison of X, Yand Yaw control techniques are presented at the end of this paper.

This controller monitors the controlled process variable, and compares it with the reference or set point. The difference between actual and desired value of the process variable, called the error signal. Error is applied as feedback to generate a control action to bring the controlled process variable to the same value as the set point. Control action in which the output is proportional to a linear combination of the input and the time rate of change of input. The primary goal of this study is to develop a mathematical model that predicts the behavior of quadcopters UAV, which are flying robots with four motors. The quadcopters are controlled by three parameters of algorithms known as PID controllers, where P is based on current errors, I is based on the accumulation of previous errors, and D predicts future errors.

The purpose is to provide a basic technique for PID controller design. Certain assumptions are made in order to build the control algorithm in this research. These assumptions include the omission of characteristics like blade flapping and surrounding fluid velocities. By ignoring these aspects, the model becomes more flexible and simpler and make the model more controllable, allowing for more efficient and easier control design without the need for expensive computations. The findings demonstrate the performance of the chosen model. Mathematical modeling and simulation of an unmanned aerial vehicle, specifically, quadrotor modeling is not an easy task because of its complex structure, nonlinear dynamics and under-actuated nature.

The aim is to model a quadrotor vehicle as realistic as possible. The model is then used to design a PID controller structure to stabilize the roll, pitch and yaw angles of the quad rotor system. The developed systems id tested successfully for number of numerical simulation runs. The paper presents a new model design method for the flight control of an autonomous quad rotor. The paper describes the controller architecture for the quadrotor as well. The dynamic model of the quad-rotor, which is an under actuated aircraft with fixed four pitch angle rotors, will be described. The Modeling of a quadrotor vehicle is not an easy task because of its complex structure. The aim is to develop a model of the vehicle as realistic as possible. The model is used to design a stable and accurate controller.

This paper explains the developments of a PID proportionalintegral-derivative control method to obtain stability in flying the Quad-rotor flying object. The model has four input forces which are basically the thrust provided by each propeller connected to each rotor with fixed angle. Forward backward motion is maintained by increasing decreasing speed of front rear rotor speed while decreasing increasing rear front rotor speed simultaneously which means changing the pitch angle. Left and right motion is accomplished by changing roll angle by the same way.

The front and rear motors rotate counter-clockwise while other motors rotate clockwise so that the yaw command is derived by increasing decreasing counter-clockwise motors speed while decreasing increasing clockwise motor speeds. Since there has been an important increase in unmanned vehicles systems research such as quadrotors, a mathematical model and PID control laws are studied. Based on some dynamic variables, PID control is applied to compute a controller to be then use in autopilot simulations. As this kind of VTOL vehicle seems to be unstable, the aim of this work is to change even other flight mechanics parameters and control gains to study attitude and altitude variations.

A well-known computational tool is used for simulation purposes, performance analysis and validation. This paper presents the development of an unmanned aerial vehicle of type quadrirotor, its dynamic model, besides simulations and tests of a PID controller for the projected structure embedded stabilization vertical direction motion. This vehicle is characterized by having four motors, which are responsible for generating the platform movement. This paper includes three main parts. The first part is about a Quadrotor as a type of unmanned vehicles. The second part includes its mathematical model and controlling with PID controller.

The last part consists of some in flight and on ground testing. For the aforesaid processes first of all a Quadrotor has been built. The Quadrotor is designed within the Anadolu University which is the unique university because of its own airport. The design has some problems such as slow vibration speed, long response time and big movements in roll axes so some controlling applications have been developed. After ensuring its stabile flight, some sensor tests have been carried out to develop its control mechanism. The paper discusses a method to measure moment of inertia of quadrotor about its principal axes to achieve better results in an inexpensive way.

We also present the trajectory generation and segment optimization of the trajectory commanded to the quadrotor. We describe a method of controlling the quadrotor through ROS by providing necessary inputs to the flight controller using the built-in firmware. The special capabilities of these, reducing radar identifier, low risk for human life, no restrictions on size and uses such as photography, survey, press coverage, checking, power lines, meteorological analysis, traffic, monitoring, in urban areas, crops and poison, spraying products, controlling country boundaries, controlling illegal imports and exports, fire detection and control, search and rescue operations for missing people and natural disasters can be mentioned, which leads to the plenty of motives for researchers.

Contains wide researchers and putting various topics in front of researchers. One of these fields is using various algorithms with the ability to use in their control system. Mainly, the PID controllers are reported by the researchers, but although the PID controller as a classic model has some restrictions, it International Journal of Wireless and Microwave Technologies, As the world is getting digital there are few things which are used as it is for a long time.

The most important thing which we do in our daily life is the transaction of money. Money transaction is a process which should be digitized for more security and the ease of the individual. So, by making a digital wallet the money transaction can be made much simpler and effortless. Using digital wallet we can keep all our important cards such as health card, driving license and other important papers in only one place with much more security. The digital wallet can be our transaction medium which can be used anywhere such as shops, malls or for giving money to someone else. And with such high security such as finger print scanning our money and all the information which the wallet is carrying will be safe.

In case, if the wallet is lost GPS will help to detect the location of our device and that what makes the wallet a digital safe.
