Preliminary Design Rules for Electromechanical Actuation Systems –Effects of Saturation and Compliances
Résumé
Electromechanical actuator (EMA) is a type of power-by-wire (PBW) actuator that is becoming widely implemented in aerospace industry. Given the application area, designing an EMA is highly constrained in weight, integration space, maintenance costs, dynamic performances, reliability, etc. In order to reduce the EMA’s design time, cost and effort, all these constraints should be considered in the preliminary design stages. The problem is that at such early design stages, system engineers need simple and explicit models. Thus, this communication is attempting to formulate simple relations that account for torque and velocity saturation of the EMA as well as compliances effects on its dynamic performance. The simple and parametric models predict the main impact of the sizing variables on performance
