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.
