This paper presents a flight rnanageiiient system (FhIS) iinpleniented as on-board intelligence for rotorcraft-based unmanned aerial vehicles (RUAVs), in order to gradually refine gilen abstract...
Counter Example for "Exponential Observers for Nonlinear Systems" (2007)
> x(t). According to the definition of \Gamma on page 484, with ffl 1 = x 1 \Gamma x 1 and ffl 2 = x 2 \Gamma x 2 , \Gamma = B(x; u) \Gamma B(x; u) \Gamma B (x; u)ffl +A(x; u)x \Gamma A(x; u)x...
H. Jin, Kim René, Vidal David, H. Shim, Omid Shakernia, Shankar Sastry
We consider the problem of having a team of Unmanned Ground Vehicles (UGV) and Unmanned Aerial Vehicles (UAV) pursue a team of evaders while concurrently building a map in an unknown environment. We...
A Comprehensive Study on Control Design of Autonomous Helicopter (1998)
H. Shim, T. J. Koo, F. Ho, S. Sastry
In this paper, we compare three di erent control methodologies for helicopter autopilot design: linear robust multi-variable control, fuzzy logic control with evolutionary tuning, and nonlinear...
A Comprehensive Study of Control Design for an Autonomous Helicopter (1998)
H. Shim, T. J. Koo, F. Hoffmann, S. Sastry
In this paper, we compare three different control methodologies for helicopter autopilot design: linear robust multi-variable control, fuzzy logic control with evolutionary tuning, and nonlinear...
Hybrid Control of an Autonomous Helicopter (1998)
T. J. Koo, F. Hoffmann, F. Ho Mann, H. Shim, B. Sinopoli, S. Sastry
This paper proposes a hierarchical hybrid architecture of a reactive system that governs the operation of a helicopter based UAV. The mission of the helicopter is to search for, investigate and...
