Modeling, simulation, and graphical visualization of a twin lift helicopter system under automatic control: an educational tool

This educational research endeavor describes the development of a Windows/C++ PC environment designed to visualize and evaluate the performance of a Twin Lift Helicopter System (TWS) under automatic control. The TLHS consists of two Sikorsky UH-60A Blackhawk helicopters, jointly lifting a heavy payload. The program-user interface permits users to change critical model and control law parameters in real-time. TLHS and control system dynamics are numerically computed and used to update graphics and animation on the screen. The utility of the program for evaluating TLHS performance and teaching fundamental systems and control concepts is discussed.
