Abstract :
A scheme for state estimation and control under information constraints is implemented for “LAAS Helicopter benchmark”. Parameter estimates of the “Helicopter” pitch dynamics model are obtained by means of the real-time identification algorithm. The hybrid continuous-discrete observation procedure for transmission of the measured data over the limited-band communication channel with adaptive tuning of the coder range parameter is proposed and used in the experiments for pitch motion control of the “Helicopter”. Experimental results for pitch motion control of the “Helicopter” are presented, showing efficiency of the proposed method.
