Robust Iterative Learning Control for Pneumatic Muscle With Uncertainties and State Constraints

“…Remark 3. In the optimization-based ILC [27][28][29], the system input, output and state constraints are transformed into matrix inequality and the control law is designed by solving the constrained optimization problem. In virtue of energy-based nature, we use CEF incorporated with BLF to handle state constraints.…”

Iteration learning control for 2D linear discrete systems with randomly varying trail lengths

“…In the light of the iterative learning control (ILC) strategy can achieve the full tracking task on a time interval under certain conditions without the precise knowledge of engineering systems, this technique has received considerable attention in recent years (Amann et al, 1996;Arimoto et al, 1984;Huang et al, 2013;Liu et al, 2014;Wang et al, 2013;Yu et al, 2016) and turned into an important research field of control theory and applied successfully to practical application (Meng et al, 2014;Yu et al, 2018). So far, combining ILC method with other control methods, a series of extensions have been made, such as proportional-integral-derivative (PID)-type ILC (Huang et al, 2013;Liu et al, 2014;Wang et al, 2013), optimal ILC (Amann et al, 1996), adaptive ILC (Yu et al, 2016), and data-driven ILC (Bu et al, 2021(Bu et al, , 2022Chi et al, 2018Chi et al, , 2019Radac and Precup, 2016). However, most of the above strategies focus on one-dimensional (1D) dynamical systems involved with only one independent variable.…”

Energy saving for building heating via a simple and efficient model-free control design: First steps with computer simulations

“…• which is inherently robust, since the perturbations are easily taken into account, -easy to implement both from software and hardware viewpoints, has already been successfully applied a number of times, and in many countries. See, e.g., the references in [21], [1] and the references therein, and [2], [5], [13], [14], [17], [18], [28], [29], [30], [35], [38], [40], [41], [42], [43], [45], [47], [48], [51], [53], [55], [56], [57], [62], [66], [68], [69], [70], [71], [73], [74], [75], [76], [78], . .…”
