Figure Legend:
Control design in presence of constraints: the gray regions indicate the limits imposed to the amplitude of the control signal u(t).
The control u(t) is designed following two different strategies: LQR with a saturation function (–) and constrained MPC (–), see Sec.
3.2.2. The LQR solution (– –) is introduced as reference. The performances of the controllers are shown in terms of rms-velocity
reduction in Fig. 14.
