Automatic Control System of Hydraulic Tension Pilot Warm Rolling Mill

Fuzzy Multiple Stand Tension Control of a Roughing Rolling Mill

∗ Previous address: Department of Automation, Tianjin University, P. R. China Abstract In steel rolling industry, control of hot metal rolling process plays an important role in assuring high product quality and safe process operation. Although many advanced looper control technologies for finishing rolling process have emerged, looperless interstand tension control of roughing rolling mills re...

Fuzzy Tuning PID Control of Strip Rolling Mill Hydraulic APC System

Hydraulic Automatic Position Control (APC) is a very important part of rolling mill for magnesium plate rolling. The control effect of automatic position control system influences the quality of the rolled product directly. APC system is an essentially nonlinear, time delay, time-varying, large inertia, multivariable and coupling complex system, which increase the designing difficulty of contro...

UIO-based Fault Diagnosis for Hydraulic Automatic Gauge Control System of Magnesium Sheet Mill

Hydraulic automatic gauge control system of magnesium sheet mill is a complex integrated control system, which including mechanical, hydraulic and electrical comprehensive information. The failure rate of AGC system always is high, and its fault reasons are always complex. Based on analyzing the fault of main components of the automatic gauge control system, unknown input observer is used to re...
