acker. Pole placement design for single-input systems. Syntax. k = acker(A,b,p) Description. Given the single-input system. and a vector p of desired closed-loop pole locations, acker (A,b,p)uses Ackermann's formula [1] to calculate a gain vector k such that the state feedback places the closed-loop poles at the locations p. The formula requires the evaluation of the first row of the matrix T c − 1 rather than the entire matrix. However, for low-order systems, it is often simpler to evaluate the inverse and then use its first row. The following example demonstrates pole placement using Ackermann's formula. Substituting this into the state equation gives us: ′ = Ackermann's Formula (by Jürgen Ackermann) gives us a way to select these gain values K in order to control the location's of the system poles.
