First, the transfer function is identified on-line.
This is identified on-line using the forgetting factor recursive least square (FFRLS) technique.
Reduced versions of adaptive NPC are also possible, which significantly reduce the number of parameters to be identified on-line.
In GPC, the model is identified on-line, which is based on the QFT input and the plant output signals.
It shows that the suppression factor can be identified on-line, but a scaling factor has to be introduced because the process derivatives can become large.
In this new MPPT system, a polynomial curve-fitting approach is employed to model the PV system whose parameters are identified on-line using a Recursive-Least-Square (RLS) algorithm.
By using a nonparametric model of the control loop, that can be easily identified on-line, various tracking problems can be cast into a unified, and easily interpreted optimisation framework.
The method is particularly well suited for embedded systems, or wherever the limits imposed by the hardware and/or software architecture are relevant, is based on a nonparametric model of the control loop, that can be easily identified on-line, and allows to cast various tracking problems into a unified optimisation framework.
Single-unit PCs were identified on-line by the presence of a brief pause in simple spikes after the complex spike.
Articles that could not be identified on-line or through the University of Leeds library were classed as unobtainable.
