Vinichenko E. Synthesis of robust control systems by rolling mills main drives with related rolling through the rolled metal

Dissertation is devoted to the decision of actual scientific task of increase to exactness of control system by rolling mills main drives with related through the rolled metal is in-process decided with the indefinite parameters of plant on the basis of robust control. A synthesis and research of dynamic descriptions of robust control by rolling mills main drives with related through the rolled metal system are executed with the indefinite parameters of plant. Formed criteria of quality of robust control, the mathematical model of the by rolling mills main drives with related through the rolled metal is improved with the indefinite parameters of plant, executed checking of the worked out models for adequacy to the real objects, executed synthesis of continuous and digital robust control, analysis of dynamic descriptions of the synthesized systems. It is shown that robust regulators are synthesized comparatively with typical regulators allow to promote exactness of control by rolling mills main drives with related through the rolled metal with the indefinite parameters of plant 1,5-1,7 times when the digital control and have a small sensitiveness to the change of parameters of the by rolling mills main drives with related through the rolled metal system. Worked out experimental setting by rolling mills main drives with related through the rolled metal and experimental researches of the synthesized systems of robust control are conducted on the worked out experimental setting.
