AVIONIC CONTROL SYSTEMS FOR EDUCATION & DEVELOPMENT

  1. 1. Presented By: Fahad Ali Amjad 12063122-027 Abdullah Mir 12063122-039
  2. 2.  This paper includes two avionic control systems.  Implemented as educational tools in the study path of Information Technology for Aerospace.  They are used in ongoing development and research projects.
  3. 3.  These exercise systems are SCS & QCS.  SCS means SEESAW CONTROL SYSTEM  QCS means QUADROTOR CONTROL SYSTEM
  4. 4.  SCS task is to stabilize the system at desired tilt angle and angular rate.  To improve the system response by tuning the controller parameters.  Sensors are used to measure the actual output of the system and feed this information back to the controller.  The controller uses this information to adjust the signal of the system accordingly.
  5. 5.  3-Axis accelerometer sensor (MMA7361L)  Driver IC for dual DC motors (TB6612FNG H-Bridge)  Data acquisition unit (NI USB-6008)
  6. 6.  Software of the SCS is implemented using LabVIEW and can be used in two main controlling tasks.  In order to stabilize the system around a desired tilt angle, a (Proportional Integral Derivative) PID Controller is used to control the rotational speed of a single motor.  In case of two motors, the PID controller will calculate the required ratio needs to be increased and decreased respectively for stabilizing the system around a desired tilt angle.
  7. 7.  The calibration of sensor is used to improve the quality of data.
  8. 8.  SCS includes how the output of the PID controller adjusts itself to the required input for stabilizing the system around a desired point.
  9. 9.  The main idea of the QCS was to design a tool to learn embedded programming in a real time environment using an application from Avionics.  In QCS, the students can do implementation step by step and test their own control algorithm to stabilize the system and later to use it in real flying quadrotors.
  10. 10.  Microcontroller UC3A Atmel.  IM (Inertial Measurement Unit) consisting of the ITG3200 gyroscope and the ADXL345 accelerometer.  Four brushless controllers using the I²C.  Uses I²C to connect all peripherals on one bus.  Minimum number of wires and drivers to run the system.
  11. 11.  Components like magnetic compass, infrared, ultrasonic and pressure sensors can be added using the I²C bus.  The microcontroller provides enough I/O lines to connect all other kind of peripheries like Bluetooth, Wifi, Camera, GPS etc.
  12. 12.  Software is designed using the Atmel Framework (Technical Library) within AVR32 Studio.  We can implement all levels of the softwares to create I²C (Inter-Integrated Circuit),USART (Universal Synchronous Asynchronous Receiver Transmitter) etc over communication protocols.
  13. 13.  The control loop operates on a sample time 10ms, fast enough for a very stable control behavior in this application.  The microcontroller could even handle a faster sample time.
  14. 14.  Mechanical design involves different versions of implementation and parameterizing of each controller for all axes separately.  In the first version, all parts of the tri-axial controller including its parameters and algorithm can be tested separately and altogether.  In the second version, the quadrotor can manipulate its orientation in all 3 rotation axes without changing the position meaning the 3 translational axes.
  15. 15.  The QCS proved to be a successful learning tool and was able to control and fly the quadrotor.  Nevertheless for an optimized flight the PID parameters had to be adapted.  One big issue of this approach was the use of I²C.
