  4. 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. 4
  5. 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. 5
  6. 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. 6
  7. 7. XCELL-60 Labelled Parts  Following is a labelled diagram of the XCELL-60 Vehicle: 7
  8. 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. 8
  9. 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. 9
  10. 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. 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. 11
  12. 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. 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. 13
  14. 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. 14
