Based on behavior-based synergetic control method, a hierarchical structure of synergetic governance is proposed for cylinder-array, which contains multi terminals: Synergy Nuclear-Control Agent-Motion Terminal structure. Synergetic governance method for cylinder-array is researched based on the structure. Employ synergetic control to motion terminal system. Control agent carries out corrections between terminals for their synchronous output. Aim to the problems output same or different physical parameters, hierarchical synergy schemes which include self-synergy and inter-synergy are proposed. Slab thickness deviation thresholds are defined so as to make a distinction among thickness deviation levels. And thickness deviation rectification rules are formulated. Synergy nuclear calculates final deviation rectification decision according to the rules. Employ the governance structure to slab thickness deviation rectification control of MDF continuous press for simulations. To test the established thickness deviation rectification synergetic governance mechanism by the system, let the simulated data and slab for experiment be detected. The dynamic surfaces of displacement output and pressure output demonstrate that the hydraulic cylinder-array's outputs are consistent with slab deviation rectification decision. Synergy nuclear could shift decision according to slab features under each hydraulic cylinder. It achieves slab thickness deviation dynamic rectifying for MDF continuous press without overshoot. The outputs of cylinder-array are consistent overall.
Keywords:continuous press; deviation rectification; synergetic governance
