Abstract: |
A method of autotuning
using an asymmetric relay with hysteresis feedback test is proposed and
developed. Then, three parameters for aperiodic
first or second order transfer functions can be obtained. After the
identification relay experiment, controller parameters are computed through
linear diophantine equation in the ring of proper
and stable rational functions. This algebraic approach for a traditional 1-DOF feedback structure generates a class of PI or PID
controllers. The pole placement principle in the methodology brings a scalar
positive “tuning knob” for additional controller tuning. A Matlab-Simulink program implementation was developed for
simulation and verification of the studied approach. Two illustrative
examples support simplicity and efficiency of the proposed methodology. |
