- The project proposal aims at the continuous development of an hierarchical primitives-based learning concept for intelligent control systems (CSs). The idea is to induce feedback CSs with a generalization capability towards tracking tasks, inspired by intelligent living beings who can extrapolate learned optimal behavior to new unseen tasks without learning by repetitions. The framework operates on three levels: L1) low level feedback CS design in model-free data-driven manner to ensure reference tracking, disturbance rejection and indirect CS linearization;L2) learning tracking tasks (in terms of CS reference input + controlled output pairs, called primitives) by repeted executions via model-free data-driven Iterative Learning Control (ILC), over the feedback CS, in terms of a given optimal criterion; L3) extrapolate the learned optimal tracking behavior to new tracking tasks, without needing repetitions. To make the above framework impactful, improvement is needed to: a) ensure strong CS linearization at lower level, in an output reference model tracking problem setting, since the generalizability of the learned tracking bevahvior relies on the superposition principle of the linear CS; b) ensure learning convergence at level L2 via ILC, while reducing the number of dedicated gradient experiments; c) deal with tracking tasks of different time length (shorter/longer) than that of the learned primtives and with operational constraints. The project’s main goals are: to improve the issues a), b), c) and to experimentally validate the hierarchical learning framework on different processes of different nature (tracking tasks are ubiquitous); publish the results in visible journals and conferences; solve the project management issues.
