4. This presentation will put a light upon how to control
helicopter using low cost sensors.
 Control technology is nested loops.
Speed, height and altitude is measured in house by vision and
IP system
This aircraft technology is needed to settle down and to
respond to the demands of a high level steering at all axis,
including address, height, longitudinal and lateral speed.

5. Introduction
 This presentation gives us the solution to the problem
of automation control at low cost modules.
In Commercial aircrafts, there are many problems,
challenges and trade-offs, like.
 In commercial aircrafts, there is a problem of weight
and cost.
 Control of vibration is quite difficult.

6. Introduction (Cont…)
 The challenge is to maintain the balance between size
and cost of aircraft.
 There is problem of fuel and flight capacity.
Flight capacity means the flight duration with a given
fuel.
 Here we shall discuss the ways to minimize all these
challenges.

7. XCELL-60 Labelled Parts
 Following is a labelled diagram of the XCELL-60
Vehicle:

8. Flight Vehicle
 XCELL-60 RC helicopter is available in avionics.
 It uses petrol as fuel instead of methanol.
 Due to usage of petrol, its speed is comparatively low
but the advantage is that the vibrations are also low.
 Petrol engine gives three times flight duration.
On a single tank, it gives eighteen minutes of flight.

9. Dimensions
Here are the major specifications of the flight vehicle:
 Diameter of rotor is 1.5 meters
 Weight is 8 kilograms
 Length is 1.8 meters.
 Flight capacity is 18 Minutes per Litre.

10. Avionics & Sensors
 Computer for data logging and sensing is any high
processing CPU equipped by wireless Ethernet and
camera multiplexing.
 Stereo vision system is used to control the velocity and
height.
 The Feedback controlled by RPM sensor connected
with feed forward term from collective pitch to
improve regulation response that makes it most
effective
10

11. Altitude Control
 Heading (y), roll (f) and pitch (q) is controlled by IP
modules.
 Maintenance of aircraft is also conducted with the
control system of aircraft.
 The second source of variation is wind magnitude and
altering the flapping characteristics of the dynamics.
 This variation occurs during a flight.

12. Horizontal Velocity Control
Velocity is implemented by two levels nested loop
structure.
Velocity errors give roll for roll control modules
Longitudinal velocity errors for pitch control modules.
12

13. Vertical Control
Vertical control takes two forms:
 One is vertical velocity regulation
 Second is height regulation.
Vertical velocity controls the feedback and sends
demand to nested loop.
It also controls the height which is available in IP
modules.

14. Conclusion
 This Presentation gives us the brief knowledge about
helicopter automation system with less cost avionics
and control systems.
 Sensing is conducted by using vision modules.
 Cheap sensing makes it quite efficient as compared to
expensive projects.
 It gives us small size with much more flight duration
and low cost.
