摘要：AbstractIn this work, the problem of designing event-triggered control strategies for disturbance rejection and reference tracking for discrete-time linear systems is addressed. Based on the Lyapunov theory, LMI-based conditions for the guarantee of perfect reference tracking/disturbance rejection under the proposed event-trigger strategy are derived. Furthermore, to avoid that the ETC strategy degenerates to a periodic one (in the case of non constant signals), a practical tracking/rejection solution considering a trade-off between the reduction of the control updates and the tolerance to a small error in steady state is proposed. The conditions are then casted in LMI-based optimization problems to compute the triggering functions aiming at reducing the control updates while ensuring the perfect or the practical tracking.
