Control system design of Palletized Loading System based on PLC and fuzzy control technology

Based on the function of Palletized Loading System and the operation principle of the self-loading and unloading system, a set of electro-hydraulic control system was designed which its core is mobile Programmable Logic Controller(PLC). For the non-linear kinematics characteristic of the self-loading and unloading mechanism, a fuzzy controller was designed with two input variables and one output variable in it and was achieved via the method of off-line inference and on-line looking up table in PLC.
