A heavy workload of the SCA-LAB is to investigate the dynamics of
rotorcraft and apply advanced control techniques for its autopilot designs.
The strong existing simulation effort is in various fidelity levels and
allows students and researchers to test various simulation and modeling
ideas.
Recent Research Topics
- Mathematical Modeling of Helicopters
- Mathematical
models of helicopters (Uh-1h,
Ah-1S, Uh-60 and A109)
are developed
in C++ and
MATLAB-SIMULINK.
- Model Fidelity Variations
- Model fidelity of the simulation
models can easily be altered through a modular object-oriented approach of
the helicopter dynamics. This allows us to research what fidelity levels are
actually required for a given requirement. Some of the recent modules
included in our library are blade element aerodynamics, Pitt-Peters and
Peters-He Inflow models, Bailey's Tail Rotor, flapping dynamics, component
interactions, ground effect models,etc.
- Control System Design for Helicopters
- Classical and
modern control theory (linear model inversion, adaptive neural network,
trajectory generation, pseudo-control hedging, etc) are applied to
simulation models. Controllers in various levels, ranging from a SCAS to an
autopilot with guidance and navigation are developed.
- FLIGHTGEAR Integration
- Flightgear is an Open-Source code for simulations. All dynamic models
developed in our lab are integrated into Flightgear to test real-time
simulation.
