Global switching regulation of input-saturated discrete-time linearsystems with arbitrary l2 disturbances

摘要

Monotonicity properties of suboptimal H∞ or minimax control are established and exploited so as to develop a suitable state-feedback switching logic for regulating input-saturated linear plants in the presence of arbitrary l2-disturbances. If the plant is asymptotically null controllable with bounded inputs, the scheme is shown to provide simultaneously global internal asymptotic stabilization and global external l2 stabilization
