%X We consider the problem concerning the control of the discrete time chaotic and hyper chaotic dynamical systems in noisy environment. Due to the ergodicity property of orbits in the chaotic attractors, including chaos and hyper chaos, an optimal control is presented to direct the orbit of the discrete time chaotic dynamical system quickly towards a pre specified neighbourhood of the target, and feedback correction is added to deal with noise. After entering the neighbourhood in which the local controller is effective, the controller consisting of small perturbations is used to stabilize the orbit in the system. The numerical simulations of controlling two typical chaotic dynamical systems, one chaotic and the other hyper chaotic, show that the combined method is effective for a wide range of discrete time chaotic and hyper chaotic dynamics.
