Exact Controllability Theorems and Numerical Simulations for Some Nonlinear Differential Equations Academic Article uri icon


  • Exact controllability problems are studied for some nonlinear systems with linear controls. The tools are contraction fixed point theorems and nonlinear semigroup properties. It is shown that under the assumptions of low order nonlinearity, reversibility and the existence of certain feedback controls, the nonlinear system is exactly controllable. The constructive aspect of the theory allows the application of numerical simulation. An analog-digital realization diagram is discussed. Accurate numerical schemes are developed, and error estimates are presented, with concrete examples to illustrate the theory.
