O. Sarrazin,H. Oberbeck,Max H?fer practice there is also a trade-off to be made between model complexity and model accuracy in that a simple model is easier to simulate and use for de-sign. Robustness to modelling inaccuracy is therefore a vital characteristic required of a controller.作者: radiograph 時間: 2025-3-22 23:23 作者: 交響樂 時間: 2025-3-23 03:20

This is primarily because any lateral motion needs the pilot to be in the loop to stabilise it. Longitudinal performance in the presence of lateral motion was evaluated and checked during piloted simulation.作者: laxative 時間: 2025-3-24 11:03

A controller is said to exhibit good robust stability if it remains stable for all variations in plant behaviour which are reasonably expected to occur. Similarly a controller is said to exhibit good robust performance if it carries on performing satisfactorily for all encountered plant variations.作者: entitle 時間: 2025-3-25 09:45

The GVAM design example presented here uses only one key parameter, namely airspeed. Each of the linear controller designs is therefore assigned to a particular airspeed range.作者: 宏偉 時間: 2025-3-25 15:26 作者: groggy 時間: 2025-3-25 16:00
