PARAMETRIC SYNTHESIS OF DISCRETE PID-CONTROL ALGORITHM BY FREQUENCY METHOD
This paper shows the feasibility and effectiveness of determining the optimal parameters of a discrete PID algorithm in a given degree of oscillation by frequency method. We propose a synthetic procedure of digital one-loop system with a discrete implementation of the PID control law to minimize the quadratic integral test based on the extended gain-phase characteristics. In this case parametric synthesis algorithms have been developed.
Keywords: digital control systems, PID control, extended gain-phase characteristic, one-loop control system, the quadratic test.
