Abstract

The controller designed according to classical or modern control theory will not satisfy the performance requirements when the controlled object in industrial field can not be described by exact mathematical model or the disturbance of the controlled system. In order to make the controlled system stable and having good performance, H^∞ control theory was put forward to solve this practical problem. Taking the position of a rolling mill as the controlled object, it was rectified by optimal engineering way. Then, three different plans were put forward according to Bang-Bang control, LQ control and H^∞ control, respectively. The result of the simulation shows that the controller designed according to H^∞ method whose robust performance and ability to restrain colors disturbance is satisfactory.
- position control,
- H^∞ control,
- LQ control,
- Bang-Bang controll
