CONTRIBUTION TO THE THEORETICAL ANALYSIS OF THE ZIEGLER-NICHOLS METHOD

Mikuláš Huba - Katarína Žáková

   The high practical significance of the I₁T_d-plant approximations has been shown by the perhaps most frequently used method for controllers tuning by Ziegler and Nichols, modified later for sampled data systems by Takahasi et al. This paper extends previous works by analysing also control structures that include I₁T₁ and more general I₁T₁T_d-system. All these approximations are used for tuning of the P and PI controllers designed for single integrator system with constrained input.
