Proceedings of the 39th IEEE Conference on Decision and Control …, 2000•ieeexplore.ieee.orgAddresses issues arising in the online adaptation of PID controller parameters. With
frequency loop-shaping principles as the underlying controller design approach, the PID
parameter adaptation can be performed directly by minimizing a suitable estimation error
with standard least-squares algorithms. A variant of such an algorithm is also proposed in an
effort to approximate the minimization of the H-infinity norm of the error operator. A numerical
example is used to illustrate the implementation of the algorithm.
