On the Control of the 2D Navier–Stokes Equations with Kolmogorov Forcing

Figure 13

A dynamic sliding mode control of a stable periodic regime at the Reynolds number in the slave system (8) to a symmetrized stable periodic state regime at in the master system (7). The controller is switched on at time t = 10. (a) The norm of the error versus time. (b) The states and versus time. (c) The states and versus time. (d) The states and versus and showing how the controller drives the states from one attractor to another attractor.
