Autotuning Principles Based on Algebraic Methods
Original language description
The paper brings a simple principle for design and tuning of SISO controllers used in auto-tuning schemes. Autotuners represent a combination of relay feedback identification and some control design procedure. First and second order models with up to three parameters are estimated by means of a single asymmetrical relay experiment. Then a stable low order transfer function is identified. Subsequently, the controller is analytically derived from gen-eral solutions of Diophantine equations in the ring ofproper and stable rational functions RPS. This approach enables to define a scalar positive parameter through a pole-placement root of the characteristic closed loop equation. A first order identification yields a PI-like controllers while a second orderidentification generates PID ones. The analytical simple rule is derived for aperiodic control response and the scalar tuning parameter m>0 is then tuned according to identified time constant of an approximated transfer function.
