    supplying a design position limit and a design rate limit of the EMA to the health management system;

    determining, in the health management system, an updated position limit of the EMA based on at least the design position limit and the fault-based position limit; and

    determining, in the health management system, an updated rate limit of the EMA based on at least the design rate limit and the fault-based rate limit.
