Controller synthesis and real-time simulation of the net recovery phase of a remotely piloted vehicle

This paper presents the controller synthesis and real-time simulation of the final net-recovery phase of a remotely piloted vehicle (RPV). The recovery configuration imposes certain requirements on the controller. Further, the inherent geometry and structure of the aircraft impose restrictions on certain state variables. The mixed H₂/H_∞ approach was adopted to synthesize the controller. The synthesized controller was discretized using standard techniques; a real-time simulation was then conducted using the detailed model of the RPV on a stand alone DSP device and the controller hooked up to the DSP through a PC.
