N2 - An adaptive fuzzy sliding mode control strategy is designed to solve the problem of nonlinear, disturbances and uncertain parameters in asymmetric hydraulic cylinder position servo control system. Variable parameters and external disturbances of the system are identified by adaptive function. Meanwhile fuzzy exponential velocity reaching law is introduced to reduce the chatting phenomenon. Simulation results show the system dynamic performance is improved, the chattering phenomenon which caused by traditional sliding mode variable structure is weakened and the proposed algorithm is feasible. The algorithm control experiment of asymmetric hydraulic cylinder was done on the DSP28335 hardware platform. The experiment proves the effectiveness of the algorithm and achieves a good control result.
