Abstract
Many self-tuning Proportional–Integral–Derivative (PID) controllers have
been proposed. However, these methods are rarely employed to actual systems
because of low reliability of an on-line PID parameter estimator. In this
work, a performance adaptive controller that has two stages of PID parameters
tuning mechanisms is proposed. One of the tuners is a 1-parameter tuner
using the recursive least squares. The other tunes PID parameters using
ordinary least squares. The effectiveness of the proposed method is evaluated
by an experimental example.
