Inferential control system has many excellent performances such as disturbance resisting and set-point tracking, however, the application is restricted when strong load disturbance exists or stable control accuracy and response speed are highly required in the system. Feed-forward control system responds quickly to the system with measurable disturbance, but the control accuracy is easily affected by disturbance, so there will be a big error if the disturbance model is not accurate enough. Compound control algorithm which combines the feedforward and inferential control algorithm is proposed in this paper. Feed-forward control algorithm is used to cancel the loadtorque disturbance. Inferential control algorithm is used to cancel the error caused by soft sensing method. It is used to control the speed control of guide disc. The accuracy, robustness and fast response of the control system are proved by simulation.

It has been a long harassment to seamless tubes production that its productivity will be largely affected by the pause caused in adjusting the craft parameters of piercer. A rebuilding method of guide disc is proposed. Load-torque is predicted by soft measure method in the model and its disturbance is canceled by the feed-forward control algorithm. As for the error caused by soft sensing method, inferential control algorithm is applied to avoid it. The compound control algorithm system works to realize the final speed control of guide disc, and its accuracy, robustness and fast response have been proved validated in simulation.
