Abstract :
This paper deals with optimal input design in conditional set membership identification. The problem is how to choose the input signal in order to minimize the global worst-case identification error. A characterization of the l∞ identification error is provided, showing that the optimal input is the one that minimizes the l∞ radius of a suitable set. Moreover, sufficient conditions under which the impulse input is optimal are given.
