Design and Development of Control System for UAV Used for Real-Time Disaster Prevention System

Abstract

Unmanned aerial vehicle has proven their usefulness in military reconnaissance in many military conflicts. The potential of Unmanned Aerial vehicle has shifted its initial focus of military applications to civil applications but it has to encounter certain issues such as precise design and development cost. This has been handled with the evolution of Hardware-in-the loop simulation techniques, which supports real-time testing, reducing the design to implementation time and cost involved. Designing a hardware-in-the-loop simulation platform allows testing the real controller or embedded control system of the helicopter under different real work load conditions. In the HILS technique, the input and the output signals of the simulator shows the real-time independent values as computation on process. In this paper, we have focused on developing UAV Helicopter that is suitable for Real-Time Disaster Prevention System. QNX Real Time Operating System was used as development environment. For the control system, the octagon embedded board with PC104 configuration was used, which provides real time simulator and multifunctional interface boards such as ADC, DAC digital input/output and serial communication interface board. The closed loop testing was carried with different data sets, duplicating GPS and Sensor data. This helps to tune the control system and upon completing the testing it can be directly fitted into the UAV on real-time.
