Abstract: In order to improve the control performance of strip rolling mill, theoretical model of the hydraulic gap control (HGC) system was established. HGC system offline identification scheme was designed for a tandem cold strip mill, the system model parameters were identified by ARX model, and the identified model was verified.

The necessary compression force is applied by hydraulic rams, or in many older mills by a screw arrangement driven by an electric motor [6]. Figure 1.

The hydraulic cylinders have an encoder to measure with each movement of the hydraulic cylinder, usually .0001". Some encoders are inside the hydraulic cylinder and some are located outside of the hydraulic cylinder. The encoder tells the position of the cylinder or the roll gap. The usual pressure is a maximum 4,500 PSI.
