Abstract:
In this paper, a robust optimal Sliding Mode Controller (SMC) based on new algorithm of Artificial Immune System (AIS) is proposed for trajectory tracking of underwatermanipulators. A new AIS algorithm is used to derive optimal values of surface parameters and boundary layer thickness inSMC with considering minimum torques and error. Surfaceparameters and boundary layer thickness are considered as antibody in AIS and Morlet wavelet is used for mutation ofthem. The simulation results show that the new algorithm is an effective method to optimal control of underwater manipulatorand decreases the cost function at least 34% in comparison with conventional SMC method.
