Basic Principles of PID Controllers

This is the simplest form of control. Here only two control positions are allowed; on or off. In the case of a valve, it opens or closes by the signal from the controller. Examples for such control system are; water level control for boiler cascade tank, air compressor cut in cut off control, temperature control for fuel oil storage tanks, etc.

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.
