disadvantage of automatic boiler control

Main Disadvantage - an overview | ScienceDirect Topics

Alexander S. Poznyak, in Advanced Mathematical Tools for Automatic Control Engineers: Deterministic Techniques, Volume 1,. 2008 Remark 19.2. The main disadvantage of Theorem 19.1 is that the solution of Cauchy's problem (19.1) exists only on the interval [t 0, t 0 + θ 1] (where θ 1 satisfies (19.5)), but not at the complete interval [t 0, t 0 + θ], which is very restrictive.
