JMAT_V3_N1_RP2 Mohammad Shahzad Journal on Mathematics 2277-5137 3 1 27 34 TDCM, LS, Synchronization, RASMC This paper investigates the synchronization of chaotic Three Dimensional Cancer Model (TDCM) with Lorenz System (LS) using a Robust Adaptive Sliding Mode Controller (RASMC) together with uncertainties, external disturbances and fully unknown parameters. The technique used for synchronization is based on simple suitable sliding surface, which includes synchronization errors and appropriate update laws to tackle the uncertainties, external disturbances and unknown parameters. All simulations to achieve the synchronization for the proposed technique for the two non-identical systems under consideration are being done using Mathematica.
