The Optimal Control Strategy for Pure Delay Inertia Process and Its Application on Strip Rolling MN-AGC System

摘要：

Through the designing of Smith predictor and controller, the second-order engineering optimal controller parameters by fixed-timing sampling are given for the controlled object with pure delay inertia link, and the explicit formulation of control law is derived. Aiming at the problem of delay time changing with rolling speed, the solution strategy of using fixed-length sampling is proposed, and the optimal MN-AGC control strategy based on fixed-length sampling is given. This optimal controller has characteristic of pure integral, whether it is based on fixed-timing sampling or fixed-length sampling.
