This paper addresses this issue and presents a novel proof of concept (POC) low-cost quadcopter UAV design approach using a systematic Model-Based Design (MBD) method for mathematical modeling, simulation, real-time testing, and prototyping.

However, the use of this innovative technology for civilian applications is still very limited in low-income countries due to the high cost, whereas low-cost controllers available in the market are often tuned using the hit and trial approach and are limited for specific applications. Unmanned aerial vehicles (UAVs), particularly quadcopters, have several medical, agriculture, surveillance, and security applications. This paper proposes an alternative approach to control attitude and altitude on a quadcopter with the NARX NN algorithm. The design was tested on a real-time simulation environment with a one-millisecond fixed-step size. Motion control performances of the PID and NARX controllers are tested on the model. In this study, PID, and NARX NN control algorithms to control the maneuvers and altitude of the quadcopter and the mathematical model have been designed on Matlab Simulink.

A dynamic time series non-linear autoregressive with Exogenous input (NARX) neural network has been chosen as an ANN controller because of the time-delayed backpropagation learning performance. Therefore, the ANN control system has been trained with the input data used with Gaussian noise and the desired target data. The most important feature of the ANN algorithms is their high performance as a result of training with different input values. The second method that has been used is artificial neural network (ANN) algorithms, which provide both advantages and convenience in defining and controlling linear systems and non-linear systems with the closed-loop feedback method used in PID. The closed-loop PID algorithms calculate the results of the system by using the error values that consist of the difference between the sensor values measured by the closed-loop feedback method and the reference inputs. The first controller is a proportional-integral-derivative (PID) controller which is a conventional linear controller.

These are the actual “How to Fly a Quadcopter” videos I was talking about.In this study, two different types of controllers have been designed and tested for altitude and motion control of an autonomous quadrotor to compare the control performance under the influence of parametric uncertainty and disturbances.

Take it slow, don’t go too far past your limits.

Fly in the morning to reduce the chances of flying in wind.

When learning to fly a quadcopter, these are the things you should do if you want to have the best experience while still flying safe.

#QUAD COPTER MANUAL#

In the video tutorials I’ll be teaching you to fly in manual mode, it’s the hardest to learn but the most fun.

Attitude (not to be confused with Altitude), also know as self-level or Auto-level.

Rate, also know as manual, hard or Acro.

There are usually 3 main stabilization modes for a quadcopter. These controls also have other names, for example: roll = aileron, pitch = elevator and yaw = rudder.

Throttle controls the up and down axis by varying the overall speed of the rotors.

Yaw rotates the quadcopter by speeding up all of the rotors spinning in on direction and slowing down all of the rotors spinning in the opposite direction.

Pitch tilts the quadcopter forward and backward the same way that roll does.

Roll tilts the quadcopter left and right by speeding up the rotors on one side and slowing them down on the other.

THE CONTROLSīelow is an example of all the controls for flying a quadcopter and how each control works. After reading this page, be sure to check out the flying lessons. These tutorials will also apply to flying any other multirotor.
