Modeling and identification of actuator for flap deflection

100%

Ulinowicz M. , Narkiewicz J.

tom Vol. 5, No. 4

35-40

The electromechanical actuator (EMA) model is presented with the methods for identifying its design parameters. The actuator is a part of the system for flap deployment on the commercial transport airplane. The differential equations with the feedback control describe behaviour of the actuator deflection. There are two concepts of drive system simultaneously considered: a high torque/low speed (HT/LS) and a geared low torque/high speed (LT/HS). For parameter identification in both cases the Maximum Likelihood (ML) method with two minimisation algorithms: linearized Gauss-Newton and Levenberg-Marquardt is applied. Both approaches for each of two design solutions were effective, while tested on hypothetical data.

The article presents the modelled system for tests and certification of the electromechanical actuators which is used in the active safety devices that increase the level of technical and fire safety. The important elements of the fire protection are: safety devices for removal of smoke and heat from the building, and devices for ensuring permeability of the evacuation tracts, and the actuators for opening the windows and valves for de-smoking and aeration. The developed system allows running tests on the actuators to determine on their load characteristics, durability and resistance to increased or decreased temperatures. The configuration of the control-measurement module includes the PC computer with implemented specialised software that cooperates with the PLC controller and allows to all necessary measurement operations and control functions that were earlier developed from the research procedures.
