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 ...
Simple approximation for designing Ackermann geometry. A simple approximation to perfect Ackermann steering geometry may be generated by moving the steering pivot points [clarification needed] inward so as to lie on a line drawn between the steering kingpins, which is the pivot point, and the centre of the rear axle.

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.
