Abstract

The nonlinear model validation techniques of open-loop and inverse simulation are introduced. The methodologies are explained and examples are given. The paper presents the results of an investigation into the use of open-loop and inverse simulation to help in the development of a nonlinear real-time helicopter model. The individual rigid body state equations in the model are simulated with the aim of producing insight into the cause of inaccuracies in the model. A suspected source of inaccuracy is verified using partial open-loop simulation. Unmodelled dynamics are represented by using the relevant flight data as an open-loop input to the simulation thus revealing the effect of incorporating those dynamics. After localising the cause of inaccuracies in the simulation model, modifications and improvements are verified using closed-loop simulation. The improvements are then evaluated by comparing results in normal and inverse simulation modes.
