Decentralised adaptive robust control schemes of uncertain large-scale time-delay systems with multiple unknown dead-zone inputs

摘要

A simple design method is presented such that the decentralised adaptive robust control schemes with a relatively simple structure can be synthesised for a class of uncertain large-scale interconnected time-delay systems with multiple dead-zone inputs. It is supposed that any information on dead-zone input non-linearities is completely unknown. On the basis of adaptive technique, a self-tuning control gain function is introduced for each subsystem to construct a simple local state feedback controller which is structurally linear in the local state variables. The simple design method presented in this study might be well understood by engineering designers, and the resulting simple control schemes can be easily implemented in a number of practical engineering control problems. By combining the presented design method with other control methods, one may expect to obtain a number of interesting results for a rather large class of uncertain interconnected dynamical systems with completely unknown dead-zone in the actuators. Finally, the simulations of some numerical examples are provided to show the design procedure of the presented method and to demonstrate the validity of the theoretical results.
