Relay-based autotuning with meromorphic control synthesis

Original language description

The paper brings a new combination of relay feedback identification and an algebraic control design method for time-delay systems. The estimation of the controlled process is performed by an asymmetric relay experiment. Then a stable first order transferfunction with a dead-time term is identified. The controller is generated by solutions of Diophantine equations in the ring of meromorphic functions. Controller parameters are tuned through a pole-placement problem as a desired multiple root of the characteristic closed loop equation. A first order identification yields a Smith-like feedback controller with a PI structure. The methodology offers a scalar tuning parameter m0 > 0 which can be adjusted by a suitable principle.
