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

Figure 9

A static sliding mode control of an asymptotically stable orbit at the Reynolds number in the slave system (8) to a symmetrized asymptotically stable 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.
