Ackermann's formula provides a direct way to calculate the necessary adjustments—specifically, the feedback gains—needed to move the system's poles to the target locations. This method, developed by Jürgen Ackermann , [ 2 ] is particularly useful for systems that don't change over time ( time-invariant systems ), allowing engineers to ...
In computability theory, the Ackermann function, named after Wilhelm Ackermann, is one of the simplest [1] and earliest-discovered examples of a total computable function that is not primitive recursive. All primitive recursive functions are total and computable, but the Ackermann function illustrates that not all total computable functions are ...

A specific application of the matched Z-transform method in the digital control field is with the Ackermann's formula, which changes the poles of the controllable system; in general from an unstable (or nearby) location to a stable location.

Wilhelm Friedrich Ackermann (/ ˈ æ k ər m ə n /; German: [ˈakɐˌman]; 29 March 1896 – 24 December 1962) was a German mathematician and logician best known for his work in mathematical logic [1] and the Ackermann function, an important example in the theory of computation.
In mathematics and logic, Ackermann set theory (AST, also known as / [1]) is an axiomatic set theory proposed by Wilhelm Ackermann in 1956. [ 2 ] AST differs from Zermelo–Fraenkel set theory (ZF) in that it allows proper classes , that is, objects that are not sets, including a class of all sets.
