Abstract

The separately excited dc motor driving a roll constitutes a mechanical resonant system due to the presence of inertias of motor and roll and elasticity of shaft. Rolling mills and manipulators are a kind of such systems and it is well known that shaft torsional oscillation tends to occur frequently when they are applied quick response PI speed control. For this reason, the control system has to be designed so that its cutoff frequency is lower than the resonance frequency. This paper proposes an effective means to control such a system. The steady-state offset error due to external disturbance and parameter variation is suppressed by an integrator inserted in series to the plant system and the speed is quickly controlled without causing the shaft torsional oscillation.
