JMAT_V4_N3_RP2 Mohammad Shahzad Mohammed Raziuddin Journal on Mathematics 2277-5137 4 3 17 24 Three Dimensional Cancer Model (TDCM), Chen System (CS), Synchronization, Robust Adaptive Sliding Mode Controller ( RASMC) In this computational research paper, the authors have synchronized the Three Dimensional Cancer Model (TDCM) with Chen System (CS) using a Robust Adaptive Sliding Mode Controller (RASMC) together with uncertainties, external disturbances and fully unknown parameters. A simple suitable sliding surface, which includes synchronization errors, is constructed and appropriate update laws are used 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. Furthermore, application to secure communication is also demonstrated on tumor cells. July - September 2015 Copyright © 2015 i-manager publications.
