Feb 28, 1996 · The generalized Ackermann's formula for standard singular systems is established in Theorem 1. The pole placement feedback gain k' can be obtained from Theorem 1 if E is nonsingular. To compute k' for the case of singular E, Theorem 2 is proposed. Theorem 1 only needs closed-loop characteristic polynomials. Jun 29, 2015 · Methods. From January 2012 to June 2013, a series of consecutive retrograde intrarenal stone surgery was prospectively evaluated at a single institute. All patients had a pre- and postoperative CT scan. The stone burden was estimated using 3 methods: the cumulative stone diameter (M1), Ackermann's formula (M2), and the sphere formula (M3). Ackermann's formula states that the design process can be simplified by only computing the following equation: in which is the desired characteristic polynomial evaluated at matrix , and is the controllability matrix of the system.
