High-fidelity rotorcraft simulation model: analyzing and improving linear operating point models

Improving a real-time helicopter simulator model with linear input filters

“…This paper is a DLR contribution to Method 2 "Black Box' Input and Output Filter Corrections' of the NATO report. At DLR experience with model fidelity evaluation and model improvements dates back many years ago, but in recent times the technique of inverse simulation evolved as the main tool in augmenting the models obtained through system identification [3,4]. In [5], inverse simulation is defined as 'a technique whereby the control actions required for a modeled vehicle to fly a specified maneuver can be established'.…”
