Design, implementation and control of a UAV blimp for photography
Abstract
Aerial vehicles as VTOL 's (VERTICAL TAKE OFF LANDING), who meet tasks such as exploration are costly in terms of maintenance and resource consumption, as commonly these work self -powered propellers, which generates high energy consumption. One solution is the use of dirigible, which are economical and effective for the task of exploration, these it possible to obtain aerial images accurately and less consumption of energy resources due to flying at a constant height and should not counteract weight, which facilitates the execution of tasks such as scanning and monitoring.

Introduction
When there is a need to carry out exploration, are required aerial vehicles type VTOL's [1], this set of vehicles are linked to problems such as high consumption of energy resources, because they are commonly supported by propellers, and these must remain moving, representing, low autonomy. In contrast an airship can travel at low speeds and can sweep an area similar to that of a VTOL, however, the advantage of going at lower speeds and no load is the low power consumption, so that autonomy could be higher and even eventually energy is taken from sunlight (photovoltaics) [2].
An airship can be static developing tasks as collection environmental data or vigilance for long periods of time, tasks in which highlight due to its low consumption of energy resources.
An alternative that reduces operating costs and increases autonomy; is the use of airships UAV (Unmanned Aerial Vehicle) [3]. The project focuses on designing, implementing and controlling a blimp UAV type.
Conclusion
The membrane material allows escapes accounting for 1% of the volume of the airship 168 hours elapsed after causing loss of lift; it is advisable to use a laminate, although the cost would raise Airship.
The airship proves to be stable this is maintained in a specific position which shows that there is no loss of balance and that the charges are located correctly.
For guidance from the IMU it is necessary to implement a complementary filter, so that the noises are eliminated, rolling and obtain a signal without delay.
The efficiency of controller was both simulation and experimental tests, the proposed PID controller was shown to have an efficient performance for controlling the orientation angles.
The autonomy of the dispositive is greater than the majority of UAVs, this was approximately 45 minutes overcoming a quadcoptero in 20 minutes, it can extend the autonomy if the airship be static at a given height.
