We investigate the null controllability property of systems that mathematically describe the dynamics of some non-Newtonian incompressible viscous flows. The principal model we study was proposed by O. A. Ladyzhenskaya, although the techniques we develop here apply to other fluids having a shear-dependent viscosity. Taking advantage of the Pontryagin Minimum Principle, we utilize a bootstrapping argument to prove that sufficiently smooth controls to the forced linearized Stokes problem exist, as long as the initial data in turn has enough regularity. From there, we extend the result to the nonlinear problem. As a byproduct, we devise a quasi-Newton algorithm to compute the states and a control, which we prove to converge in an appropriate sense. We finish the work with some numerical experiments.

Initial condition $y_0$
Cross sections $x_1 = 0.9$ of the control components
Cross sections $x_1 = 2.1$ of the control components
Cross sections $x_1 = 0.9$ of the state components

Time evolution of the control (left panel) and state (right panel) norms. We referred to the sum of the norms of the components as "Modulus"
The control components at time zero
Heat maps of the control components at $t = 0.15.$
