Plug-in Direct Particle Swarm Repetitive Controller (PDPSRC) and Plug-in Direct Multi-Swarm Repetitive Controller (PDMSRC) represent a novel (2013) approach to repetitive process control. Please see inside the m-files for more information. This submission enables you to play with the single-swarm controller as well as the multi-swarm one. The solution was inspired by the concept of iterative learning control (ILC). This project might be of your interest if you deal with: repetitive process control, iterative learning control, dynamic optimization problems, particle swarm optimization. Such control tasks are often encountered in robotics and power electronics. For more details please see http://dx.doi.org/10.1515/bpasts-2015-0098 (B. Ufnalski and L. M. Grzesiak, Plug-in direct particle swarm repetitive controller with a reduced dimensionality of a fitness landscape -- a multi-swarm approach).
