Abstract
A system and method are provided for supplying electromechanical actuator (EMA) health status information to a control system. A determination is made as to whether the EMA has experienced a fault. If the EMA has experienced a fault, a fault-based position limit and a fault-based rate limit of the EMA are determined, based on the fault. A design position limit and a design rate limit of the EMA are supplied. An updated position limit of the EMA is determined based on at least the design position limit and the fault-based position limit, and an updated rate limit of the EMA is supplied based on at least the design rate limit and the fault-based rate limit.
