Here I am. Even though I did not care much about this blog here I want to present a very new project. I am going to build a Unmanned Aerial Vehicle which its flight control system is based on sliding mode control. The UAV will be a quadcopter but the airframe hasn’t bought yet. So far I’ve built only a home-lab power supply ( a new one it would have cost me several hundreds of euros) and I am able to control in a open loop way the speed of one engine (HK turnigy) by mean of microcontroller ( for timing reason I have chosen an Arduino 2009 but as I find more time I will upgrade the code into a dsPIC33 or STM32 Cortex M3 MCU). Least but not last I want to thank the engineer Mr. Marco Brunengo for his help over electronic design phase.
